What is it?

Aegis Authenticator is a 2FA app for Android that generates one-time codes for online services supporting HOTP and TOTP. Its vault is encrypted with AES-256-GCM and can be unlocked with a password (scrypt) or biometrics backed by the Android Keystore.

Beyond basic code generation, Aegis offers many ways to add entries, including scanning a QR code or image, entering details manually, and importing from a range of other authenticator apps such as Google Authenticator, Authy, andOTP and FreeOTP. Entries can be sorted, grouped, searched, and given custom or automatically generated icons, and icon packs are supported.

The app also provides encrypted or plaintext export, automatic vault backups to a chosen location, screen capture prevention and tap-to-reveal codes. It is available on Google Play and F-Droid.
