Aegis Authenticator: Android authentication codes and vault backups
Manage two-step verification codes with Aegis on Android, export an encrypted vault and check recovery before replacing your phone.
What is Aegis Authenticator used for?
Aegis Authenticator is a free, open-source Android app for HOTP and TOTP codes. It stores account secrets in a vault and supports password encryption and optional biometric unlocking. It is not a password manager, a passkey provider or an account recovery service.
Use it for services that accept authenticator codes. Keep the vault password accessible through a separate protected route. A fingerprint is convenient on the current device, but it does not replace the password needed to import an encrypted backup.

Prepare recovery before changing phones
Begin with a noncritical account. Enable vault encryption, add the account and confirm that its code completes a real sign-in on the legitimate service. Keep the service’s recovery codes separately; a QR code used for setup contains a secret and must not appear in screenshots shared with others.
Export an encrypted vault and copy it to protected storage outside the phone. Test importing on a trusted spare Android device without deleting the original vault. Confirm a sign-in before retiring the old device. For time-based codes, check the device clock if codes are rejected.
Download Aegis Authenticator from the official website

Limitations and data protection in Aegis Authenticator
Aegis is Android-only. It does not directly connect to cloud providers: automatic remote storage depends on a compatible Android storage provider or a separate transfer app. A local backup alone will be lost with the phone.
Plaintext exports expose authentication secrets. An encrypted export uses the vault password, so forgetting it can prevent recovery. Codes can still be stolen by phishing; never enter one because an unsolicited support message requests it. Keep account recovery options available.
Alternatives for related tasks
KeePassXC manages passwords on desktop systems; Aegis focuses on Android authentication codes. Syncthing can transport a backup folder but does not prove that its vault can be imported. Verify recovery separately from synchronization.
Questions and answers
Does Aegis work on iPhone?
No. The official project supports Android and states that it has no plans for other platforms.
Are export and automatic backup different formats?
No. The official FAQ says they use the same vault format; export is manual and backup is automatic.
Can biometrics replace my backup password?
No. Keep the vault password: encrypted exports use it, and another device needs it to import the vault.
