    KeePassX is easy-to-use, cross-platform, free and open source (FOSS) that allows you to store all of your passwords in one secure, portable database.

    Required reading

    What you will get from this guide

    • The ability to save all your passwords in one convenient and secure database
    • The ability to create and store many strong passwords without having to remember them

    1. Introduction to KeePassX

    In the sections that follow, you will learn how to:

    • Set a master passphrase
    • Save your newly created database
    • Generate a random password for a particular service
    • Extract passwords from KeePassX when you need them
    • Change your master passphrase

    If you use KeePassX consistently for a particular account, you never actually have to know (or even see) your password for that application or service. The tool's copy/paste function takes care of moving the relevant password from the database to the required login form, then wiping it from clipboard memory. If, for example, you take advantage of the Random Password Generator feature of KeePassX, then configure an account to use the generated password, you will be relying on a strong password that you never actually have to look at or memorize. But it will still work! Just remember to backup your KeePassX database!

    1.0 Things you should know about KeePassX before you start

    KeePassX is a powerful, easy-to-use tool that helps you store and manage all your passwords in a highly secure database. You can put both that database and the KeePassX program on a USB memory stick and carry it with you. You can also make multiple copies of your database as backup copies to access from different devices, portable media, or the cloud. The database is protected by a master passphrase that you create. This password is also used to encrypt the entire contents of the database. You can store your existing passwords in KeePassX and have it generate new passwords for you. KeePassX doesn't require any prior configuration or specific installation instructions. It's ready to go when you are!

    1.1 Other tools like KeePassX

    KeePassX is cross-platform, which means it is also available for GNU Linux and Windows (in the KeePassX version). However, if you wish to try other similar programs we recommend:

    • 1Password is a commercial product available for Mac OS X, Microsoft Windows, iPhone and iPad.
    • KeePass 2: available for Windows and Linux (from the software centre). The database format is not compatible with KeePassX

    2. Download and install KeePassX

    2.1 Download KeePassX

    Step 1. Go to the KeePassX Website. To ensure you are at the secure https version of the site, click here or manually enter the full address manually.

    Step 2. Click the Downloads link in the menu on the left side of the page.

    Figure 1: KeePassX home page

    Step 3. Click on the MacOS X Binary Package link to download KeePassX.

    Figure 2: KeePassX downloads page

    Step 4. Save it to your Downloads folder.

    Figure 3: Saving the KeePassX .dmg file

    2.2 Install KeePassX

    Step 1. In the Finder window, find the downloaded file and double click to mount it as a disk image. It will show up under Devices in the sidebar of the Finder window.

    Figure 1: Locating the downloaded KeePassX .dmg file

    Step 2. In this guide, we'll be installing KeePassX in the Applications folder of the desktop. But remember that you can also install and use it on portable media, such as a USB flash memory stick or external disk drive. If you choose install it on a USB flash memory stick, you will be able to launch the application using other computers with compatible operating systems. (Since it is a cross-platform tool, you can also save a version of KeePassX for each operating system on your USB drive along with your personal database, enabling you to open and use your database on any other computer.)

    Using the example in this guide, please drag the KeePassX icon into the Applications folder.

    Figure 2: Dragging the KeePassX app into Applications

    Step 3. Before we start using KeePassX, we should unmount (or 'eject') the KeePassX disk image. Find KeePassX-0.4.3 under Devices in the Finder sidebar. Click on the {eject} icon next to it in the sidebar to unmount the disk image.

    Figure 3: Unmounting (or ejecting) the KeePassX disk image

    3. Create and save a new KeePassX database

    3.1 Create a new KeePassX database

    Step 1. In the KeePassX menu, select File, then New Database.

    Figure 1: Selecting New Database in the KeePassX menu

    Step 2. Choose a strong and memorable master passphrase, then enter it.

    It is very important that your master passphrase be unique, long, complex, and difficult to guess. Unfortunately, it must also be memorable. (After all, you can't keep your KeePassX master passphrase inside KeePassX, and writing it down defeats the purpose of using an encrypted password database.) If you forget it, however, you will lose access to everything in your database. So, take your time and come up with a good one! If you need help, refer to the tactics guide Create and maintain secure passwords.

    Figure 2: Setting a master passphrase for a new database

    Step 3. (Optional) If you want to see the master passphrase you have chosen and entered, you can click the {‘eye' button} to the right of the entry field. (Be aware of your current circumstances, however. An untrusted person nearby may see your exposed master passphrase!) To re-hide your master password, click the {'eye' button} again.

    Figure 3: Revealing your password using the ‘eye’ button

    Step 4. Click {OK} to proceed.

    Step 5. Enter your chosen master passphrase a second time to make sure you got it right. Click {OK}.

    Figure 4: The password re-entry window

    Step 6. (Optional) If the two entries don't match, click {Back} and re-enter your password, then follow steps 3 through 5.

    3.2 Save your new KeePassX database

    Congratulations, you have almost created a new KeePassX database. Now you must name and save it, just like you would any other electronic document. Otherwise, your database and any entries you create in it will be lost. (You can tell that a new database is unnamed and unsaved by seeing “[new]“ in the top title bar.)

    Figure 1: A new unnamed, unsaved database

    Step 1. In the KeePassX menu, select File > Save Database As.

    Figure 2: Selecting Save Database in the KeePassX menu

    Step 2. In this example, we’ll save our KeePassX database in Documents, but you can put it anywhere.

    Tip. If you store it on a USB flash memory stick, along with a copy of the KeePassX application, you will be able to access and use your database using other computers.

    We’ll also name our database passwords.kdb in this example, but you can name it anything you like.

    Tip. If you are worried that someone with access to your computer might see this file and demand that you tell them your master passphrase, you should probably come up with a less conspicuous name.

    Type in a name for your KeePassX database and {click} Save.

    Figure 3: The ‘Save Database As’ window

    Note: The database no longer has “[new]“ in the top title bar. This has been replaced by the path to your new database, ending with the name you gave it. This means your database has been saved.

    Figure 4: A saved database with a name

    Step 3. Now that you have saved your KeePassX database, let’s be sure you can find and re-open it using your master passphrase before we start adding new password entries to it.

    There are three ways to close your database: You can click the {red button} in the top left corner of the database to close it.

    In the KeePassX menu, you can select File, then Close Database.

    Figure 5: Selecting Close Database in the KeePassX menu

    Or you can use the Close Database shortcut key combination: Command-W. (The Command keys have this symbol: ().

    Step 4. Now let’s find and re-open your new KeePassX database with your master password.

    Find your database in the Documents folder (or wherever you chose to save it). Open it up by either double-clicking the file, or by selecting the file and using the shortcut key combination Command-O.

    Tip: If your Finder Preferences (Finder Preferences > Advanced) are set to ‘Show all filename extensions’, your database will have a ‘.kdb’ filename extension. In this example, it will show up in your Documents file as passwords.kdb.

    Figure 6: Locating the KeePassX database named ‘passwords’ in Documents

    Congratulations! You are now ready to start using your new KeePassX database!

    Tip: If you were unable to open your database because you forgot the master password, there is no way to open your data base, and there is no way to reset or retrieve your master password. If you are unable to remember it, you can create a new database and delete the first one.

    4. Creating and Managing Password Entries

    4.1 Create a new entry

    Step 1. The New Entry screen lets you add account information, passwords and other important details into your newly created database. In the example that follows, we will create an entry in which to store your password for the RiseUp email service.

    In the KeePassX menu, select Entries, then Add New Entry. Or you can use the Add New Entry shortcut key combination: Command-Y.

    Figure 1: Selecting ‘Add New Entry’ in the KeePassX Entries menu

    Step 2. Learn about the various elements in a KeePassX entry.

    The Add Entry window presents you with a number of fields to be completed. None of these fields are mandatory; information submitted here is largely for your own convenience.

    Figure 2: The New Entry window in KeePassX

    A brief explanation of the text fields and elements in a KeePassX entry is presented as follows: - Group: KeePassX lets you sort your passwords into pre-defined groups. For example: 'Internet' would be a good place to store passwords that relate to website accounts. Click on the drop-down menu to choose a group. - Icon: The icon that will be associated with this account entry. If you click on the icon button, you can see the icons available in the Icon Selection window. You also have the option to add a custom icon by clicking on the ’Add Custom Icon’ button in the bottom left of the Icon Selection window. To select one of the KeePassX icons available, click the Pick button in the bottom right of the window.

    Figure 3: The Icon Selection window

    • Title: A name to describe the particular password entry. For example: ‘Gmail password’.
    • Username: The user name associated with the password entry. For example: ‘’.
    • URL: The website associated with the password entry. For example: ‘'.
    • Password: This field has two options: the ability to enter a password that you have created, or the option of generating a new password using the Password Generator, which is the button with the eye symbol to the right of the password text field. Generating a random password on request using the Password Generator will be described in the following section. If you are creating an entry for an account that already exists, you will want to enter the correct password here.
    • Repeat [Password]: The confirmation of the password.
    • Quality: A progress bar that measures password strength in bits according to length and randomness. The fuller the quality bar becomes (and the more bits there are), the stronger your chosen password is.
    • Comment: Here is where you type in descriptive or general information about the account or site for which you are storing information. For example: Mail server settings: POP3 SSL,, Port 995; SMTP TLS,, Port: 465. Or Security Question and Answer: Q: Where were you born? A: Jupiter. Your Comments will be encrypted, along with your passwords, when you close the database. While it is open, however, your notes may be visible to anyone who can see your screen.
    • Expires: KeePassX can remind you to change your password after a certain length of time. If you want to set an expiration date, click the "clock" button to specify an expiry date. By doing this, you can add a reminder for yourself to change the password at a specific time (every 3 months, for example).
    • Attachment: Any file related to this account entry that you want to keep secure and associated with the entry. KeePassX will encrypt this file when you close your database. Click the first button to the right of the Attachment field to add a file. Examples of attached files could include a list of confidential contacts for that account, or confidential financial information.

    Note: Creating or modifying the password entries in KeePassX does not change your actual passwords! Think of KeePassX as a secure electronic address book for your passwords. It only stores what you write in it, nothing more.

    Step 3: Create a new KeePassX entry for your RiseUp account within the Internet Group in your KeePassX database. Select Internet from the Group dropdown menu. Then enter the account information for your RiseUp account.

    Your entry will resemble the following:

    Figure 4: New Entry screen in KeePassX with unsaved account information

    Note: If you’d like to generate a new random password for this entry using KeePassX’s Password Generator, scroll down to section 4.2 before saving your entry in Step 4 below.

    Step 4: Click {OK} to save your changes to the Add Entry screen.

    Your RiseUp password entry now appears in the Internet group.

    Figure 5: The KeePassX database window

    Note: The bottom panel of the database window displays information about the entry selected. This includes creation, editing, expiry date, and any comments you may have recorded in the entry. It does not reveal the username or the password. If an entry has expired, it will only show up in this bottom panel with [Expired] (denoted by the red arrow in the figure below).

    Figure 6: An example of an expired key in the database window

    4.2 Generating Random Passwords Using the Password Generator

    Using long, memorable passphrases or generating and using long, random passwords will help keep your accounts secure. Long, random passwords based on mathematical principles cannot simply be 'guessed' by someone who is trying to break into one of your accounts. KeePassX supplies a Password Generator to help you with this process. This section will describe how to generate one yourself.

    Step 1. Access the Password Generator using one of four options:

    Options 1 & 2: The Password Generator can be activated from within the Add Entry and Edit/View Entry windows by clicking the ’Gen’ button to the right of the Repeat password text field.

    Figure 1: A KeePassX entry accessed using the Edit/View Entry option

    Options 3 & 4: Alternatively, you can also access it via the KeePassX menu by clicking on Extras, then selecting Password Generator. Or you can use the Password Generator shortcut key combination: Command-P.

    Figure 2: Accessing the Password Generator using the Edit/View Entry option

    Figure 3: The KeePassX Random Password Generator

    The Password Generator presents a variety of options for generating a password. We’ll be using its Random Password Generator in this example. You can specify the length of the desired password, the types of characters from which it will be created (such as numbers, special characters, uppercase and lowercase letters), and much more. For our purposes, we can use the default options presented. This means that the generated password will be 25 characters long and made up of lower and upper case letters, numbers, and special characters.

    Step 2. Click the Generate button to create a randomly generated password. When complete, KeePassX will present the generated password to you in the New Password text field, but it will be hidden. (The only exception to this is if you accessed the stand-alone Password Generator using Options 3 & 4 above. In this case, you’ll have to copy and paste the new password in manually.)

    In most cases, long, randomly generated passwords aren’t memorable. But with KeePassX, you can generate, securely store, and use these strong passwords for your accounts to keep them safe. Therefore, in most cases, you’ll never need to even look at long, randomly generated passwords like this! (But you will need to copy and paste these passwords into your various accounts, which we’ll cover in section XX below.) In the image below, the new randomly generated password is revealed in order to illustrate the tool:

    Figure 4: An exposed password in the KeePassX Random Password Generator

    Note: You can view the generated password by clicking the ’Eye’ button to the right of the New Password text field. But be aware that this may create a security risk if others can see your new, strong, randomly generated password!

    Step 3. Click OK to accept the password and return to the Add Entry screen as follows. Your new randomly generated password will now be added into your KeePassX entry for you. (If you had another password before generating this new password, it will be replaced by the new password you’ve just created using the Password Generator.) In the image below, the password text field has been revealed in order to illustrate this.

    Figure 5: KeePassX Entry with revealed password copied over from the Password Generator

    Step 4. Click OK to save the KeePassX entry.

    4.3 Edit an existing entry

    You may edit an existing entry in KeePassX at any time. You can change your password or modify other details stored in the password entry. It is generally considered good security practice to change a password every three to six months (remembering to also update it on your email system and elsewhere as well).

    To edit an entry, perform the following steps:

    Step 1. First, Select the ’Internet’ Group in the database menu on the left side of the window to see the entries associated with it.

    Figure 1: Choosing a group in the main KeePassX database window

    Step 2. In this example, we’ll use the Riseup account entry we created in Step 4.1 above. Within the ’Internet’ Group, Select the Riseup entry we created by clicking it within the list of entries inside the ’Internet’ Group (at the moment, it’s the only entry in your new KeePassX database, but eventually your database will have many entries within each group).

    Figure 1: Selecting an KeePassX entry in the main KeePassX database window

    Step 3. There are three ways to open up the entry in order to edit it.

    Option 1. You can ‘right click’ on the selected entry by holding down the Control key and clicking the entry, which activates a menu of options.Then scroll down and click on View/Edit Entry.

    Figure 2: The ‘right click’ menu for a KeePassX entry

    Option 2. In the KeePassX menu, select Entries, then New Database.

    Figure 3: Selecting ‘View/Edit Entry’ from the KeePassX menu

    Option 3. Use the View/Edit Entry shortcut key combination: Command-E.

    Step 4. With an open entry, you can add new information or edit any existing information, including the password. (In this example, we’ll add some additional information to the Comment field.) To save your changes, click {OK}.

    Figure 4: Saving edits to a KeePassX entry

    Note: Remember that making changes to a KeePassX entry only updates that entry in your KeePassX database. It does not automatically update corresponding information elsewhere, such as a new password for an online account, or the same KeePassX entry in any copies or backups of your KeePassX database that you have saved elsewhere. Therefore, you will need to make any relevant updates to your account information, as well as new KeePassX database backups and copies seperately after editing your entry here.

    5. Using your entries in KeePassX

    One of the best features of KeePassX is that it safely stores long, strong passwords for you so you don’t have to memorize them or reuse passwords for multiple accounts (which is risky). KeePassX lets you copy your usernames and passwords from the database and paste them into your accounts. For greater security, a copied password will only remain in your digital clipboard for about 10 seconds, so it will save time to have your account or website already open and running, so that you can paste the relevant usernames and passwords there as required.

    5.1 Sign into an account using KeePassX

    In this example, we’ll sign into our RiseUp email account by copying and pasting our password from our new KeePassX entry. Remember that you can also copy and paste your User Name and other information from your KeePassX entries as well!

    Step 1. In the main KeePassX database, select the Group where your RiseUp Entry is stored. (In our example, this is the Internet Group.)

    Step 2. There are three ways to copy the password from a KeePassX Entry to the clipboard.

    Option 1. Right click (Command and click in Mac OS X) on the required password entry to activate a drop-down list of menu options. Scroll down and click on Copy Password to Clipboard.

    Figure 4: Copying an entry’s password using the right-click menu in the main KeePassX database window

    Option 2. As you saw in the right click menu above, the Copy Password to Clipboard shortcut key combination is the customary one used for copying: Command-C.

    Option 3. Finally, you can use the main KeePassX menu by clicking on Entries, then scrolling down to select Copy Password to Clipboard.

    Figure 5: Copying an entry’s password using the main KeePassX menu

    Step 3. Go to the related account or site and paste the password into the appropriate field:

    Figure 6: A RiseUp Email Account displaying a pasted password

    Tip: For efficient copying, pasting and switching windows, use the keyboard shortcuts. Press and hold the Command key, then press C to copy a password. Press and hold the Ctrl key, then press V to paste that password. You can also Press and hold the Command key, then press the tab key to switch between open programs and windows.

    Note: By using KeePassX all the time, you never actually have to see or know what your password is. The copy/paste functions take care of moving it from the database to the required window. If you use the Password Generator feature and transfer your newly generated password using using the copy/paste functions when you register for new accounts, you will be using a password that you have never seen in plain view. And it still works!

    6. Manage your KeePassX database

    6.1 Locking, Minimizing, and Closing KeePassX

    KeePassX is designed to lock your database for safety reasons, so unauthorized users won’t gain access to the sensitive information inside. When the KeePassX database is locked, you will be prompted to enter your Master Password in order to unlock and access it again.

    By default, KeePassX databases will lock after 600 seconds of inactivity. You also have the option to have your database lock whenever you minimize it, but this is not the default setting in KeePassX.

    Optional: You can change these options (and many others) in the KeePassX Settings. You can access the settings in the main KeePassX menu by clicking on KeePassX, then scrolling down to select Preferences. Or you can use the Preferences shortcut key combination: Command-,.

    To access the database lock options within Settings, select Security in the left-hand list of categories.

    Figure 1: KeePassX Security Settings window

    Step 1. KeePassX also lets you lock the program manually. Practice locking and unlocking your KeePassX database using one of the options available. You can click on File, then scroll down to select Lock Workspace. Or you can use the Lock Workspace shortcut key combination: Command-L.

    After you’ve locked your KeePassX database, it will display two options: Unlock (to unlock the database), and Close Database (which will require you to open the database again).

    Figure 2: Locked KeePassX database (or ‘workspace’)

    6.2 Backup your KeePassX Database

    The KeePassX database file on your computer is denoted by its .kdb file extension. You can put both that database and the KeePassX program on a USB memory stick and carry it with you. You can also make multiple copies of your database as backup copies to access from different devices, portable media, or the cloud. Since the database is protected by a master password that you create, no one else will be able to open the database without it.

    Step 1. To make a backup or second copy of your database, click File in the main KeePassX menu, then scroll down to select Save As. This will allow you to name and save a copy of the database.

    Tip. KeePassX does not automatically update all copies of a database when changes are made. You have to do this manually. It’s a good habit to regularly replace backup copies of your KeePassX database. That way you won’t lose any edits or new entries if you lose your main database!

    6.3 Resetting your Master Passphrase

    You can change the Master Password at any time. This can be done once you have opened the password database.

    Step 1. In the main KeePassX menu, Select File, then scroll down to select Change Master Key.

    Figure 1: The Change Master Key screen in KeePassX

    Step 2. Type in the new Master Password twice when prompted to do so.


    KeePassX is a very easy program to use. The important part is getting into the habit of creating new passwords in KeePassX. It may be difficult to get used to the fact that you never have to see a password again, but it is definitely easier than having to remember them!

    Q: On the outside chance that I forget my master password, is there anything I can do to access KeePassX and retrieve my password databases?

    A: No. There is nothing you can do in that situation. On the bright side, at least no one else will be able to access your password database! To prevent this from happening, you could use some of the methods for remembering a password or passphrase that are described in the Create and maintain strong passwords guide.

    Q: And if I uninstall KeePassX, what will happen to my passwords?

    A: The program will be deleted from your computer, but your database (stored in a .kdb file) will remain. You can open this file at any time in the future if you install KeePassX again.

    Q: I think I accidentally deleted the database file!

    A: Hopefully, you made a backup beforehand. Also, make sure you haven't simply forgotten where you stored the file in the first place. Search your computer for a file with a .kdb extension. If you really have deleted it, you may be able to use recovery software to recover the file.
