Aegis Authenticator (Android)
Your 2FA codes on Android, encrypted locally. No cloud, no account. Open source.
Description
Aegis keeps your 2FA codes on your Android phone, encrypted, without ever sending them to the cloud. No account to create, no automatic sync: you decide when to export an encrypted backup. The app is open source, free, and highly regarded in the privacy community. The flip side: if you lose your phone without a backup, your codes are gone.
