Aegis Authenticator review

Aegis Authenticator is the best option for Android users who want their codes on their own terms. Tokens live in an encrypted vault on the phone with optional biometric access, and there is no vendor cloud at all: automatic backups go to a folder you choose, and on cloud providers that support Android's Storage Access Framework, such as Nextcloud, that can be an off-device location. Manual vault exports are supported too. Aegis is generous on the way in, importing from Authenticator Plus, Authy, andOTP, FreeOTP, Google Authenticator, Microsoft Authenticator, Steam, TOTP Authenticator and WinAuth, though some imports need root. The interface supports Material You, a true dark mode, a tiles view and icon packs. Aegis is free, open source and available on Google Play and F-Droid, with 675K+ installs reported by the project. Its limit is reach: there is no iPhone or desktop version, so mixed households will want Ente Auth or Proton Authenticator.
