# Aegis Authenticator

> Aegis (v3.4.3, Sep 2026) is an Android-only two-factor code app, GPL-3.0. Codes live in a local vault encrypted with AES-256-GCM, unlocked by password or biometrics, with automatic backups to a location you choose. It imports from Google Authenticator, Authy, 2FAS, FreeOTP and others. No cloud sync, no iOS or desktop app, and it does not store passwords. The vault format and security design are documented publicly; we found no third-party audit report.
