Aegis Authenticator
/ identityAegis Authenticator is the gold standard for 2FA on Android, fixing the glaring flaws of apps like Google Authenticator. It is fully open-source and, crucially, does not request internet permission—meaning it is physically incapable of leaking your 2FA tokens to the cloud. Your secrets stay on your device, encrypted at rest using AES-256.
A stand-out feature is its robust backup system. Aegis can automatically create encrypted backups of your vault, allowing you to easily migrate to a new phone or recover from data loss without locking yourself out of your accounts. With support for organizing tokens into groups and custom icons, it combines hardcore security with a pleasant user experience.
