FAQ

How can I add a token? You can import QR codes or enter the token details manually. Furthermore 2FAGuard supports importing multiple tokens at once from other 2FA apps. All tokens that follow the TOTP standard are supported.

How is my data secured? The secret keys, the account names and your notes are encrypted using the AEGIS-256 algorithm. The encryption key is derived via Argon2id.

From which 2FA apps can I import tokens? Tokens can be imported from generic TOTP Uri lists. In addition Google Authenticator, Bitwarden, Authenticator Pro and 2FAS are currently explicitly supported.

Which devices are supported? This app is only available for Windows 10 18362.0 and higher. For Android I recommend Authenticator Pro that is fully compatible with 2FAGuard.
