A free, secure and open-source 2FA app for Android, with encrypted vault backups and Steam/DigitalOcean support.
Local-only 2FA authenticator. Vault is encrypted at rest; no trackers and no unnecessary network access. A model of minimal permission design.
Aegis is a two-factor authentication (2FA) app that generates one-time codes for your accounts. It supports TOTP as well as the proprietary algorithms used by Steam and DigitalOcean, and can import from most other authenticator apps. Your vault is encrypted at rest with a strong password or biometric unlock — by default, entries cannot be read without it. Backups can be exported in a standards-compatible, encrypted format and slotted into any file sync or backup tool you already use. Aegis is open source (Apache-2.0), regularly audited by the community, and contains no ads, trackers, or network permissions beyond optional crash reporting.
