Source: https://altcatalog.com/alternatives/aegis-authenticator/ Category: Authenticator apps ## Overview - **Who it's for**: Android users who want a free, open-source 2FA app instead of Google Authenticator or Authy, particularly those who prioritize privacy, data ownership, and control over their credentials. - **What you get**: Aegis stores TOTP and HOTP tokens in an encrypted vault that unlocks with a password or biometrics. It supports encrypted backups and exports you control, importing tokens from other authenticator apps, and organizing accounts with groups, icons, and search. The app requests minimal permissions and works fully offline. - **How it works**: Unlock the vault, then add accounts by scanning a QR code or importing from another authenticator app. Aegis generates time- or counter-based codes automatically, and you can periodically export an encrypted backup to keep your tokens safe across devices. ## Profile - **License**: GPL-3.0 (verified 2026-07-11) - **Pricing model**: Free (verified 2026-07-11) - **Starts at**: ? - **Platforms**: Android - **Status**: active (verified 2026-07-11) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [2FAS](https://altcatalog.com/alternatives/2fas.md) | 85 | GPL-3.0 | iOS, Android, Browser extension | | 2 | [Stratum](https://altcatalog.com/alternatives/stratum.md) | 75 | GPL-3.0 | Android | | 3 | [Ente Auth](https://altcatalog.com/alternatives/ente-auth.md) | 70 | AGPL-3.0 | iOS, Android, Windows, macOS | | 4 | [Authy](https://altcatalog.com/alternatives/authy.md) | 55 | Proprietary | iOS, Android | | 5 | [Duo Mobile](https://altcatalog.com/alternatives/duo-mobile.md) | 55 | Proprietary | iOS, Android | | 6 | [FreeOTP](https://altcatalog.com/alternatives/freeotp.md) | 55 | Apache-2.0 | iOS, Android | | 7 | [Google Authenticator](https://altcatalog.com/alternatives/google-authenticator.md) | 55 | Proprietary | iOS, Android | | 8 | [Microsoft Authenticator](https://altcatalog.com/alternatives/microsoft-authenticator.md) | 45 | Proprietary | iOS, Android | | 9 | [Yubico Authenticator](https://altcatalog.com/alternatives/yubico-authenticator.md) | 40 | Apache-2.0 | iOS, Android, Windows, macOS | Alt Score = Verified coverage (90%) + Visibility (10%).
