Quick security recommendations for your devices

People often ask us where they can start, what are minimum steps they should consider taking in an effort to better protect their devices. In this post we share what we are recommending as the first, often most effective and most important items.

General

  1. Use unique and strong passwords for each account, using a password manager to safely store them.
  2. Use two-factor authentication (2FA) on supported accounts. As a first choice, consider using hardware devices (also called security keys). Otherwise you can also use apps or programs that generate time-based one-time passwords (TOTP). Avoid using SMS for 2FA if you can.
  3. Avoid using biometrics (face ID, fingerprint scan) as an authentication method. We explain why in the guide on passwords.
  4. Delete old files, documents, pictures, screenshots and chat history that you do not need on your device. Securely back up as necessary before removal.
  5. If you can, avoid installing social media apps: you can use them by accessing their website with your browser instead.
  6. Restart your device frequently. This ensures updates are applied properly and reduces the risk for cases of non-persistent malware.

  2. Automatically update your apps.
  3. Enable Play protect.
  4. Review the permissions your apps have access to.
  5. Review installed apps and uninstall any unneeded/unknown ones.
