While we cannot provide an exhaustive list, here are some commonly used authenticator apps that are known to work with FusionAuth:

  • Google Authenticator
  • Authy
  • Microsoft Authenticator
  • LastPass Authenticator
  • 1Password

Compatibility Check:

If an authenticator app does not support FusionAuth’s TOTP, it will simply fail to recognize the QR code when scanned.

Documentation Reference:

For more details about FusionAuth's TOTP implementation and requirements, refer to the FusionAuth TOTP Documentation.

Most users should have no issues using any modern TOTP-based authenticator app.
