Aegis Authenticator is a free, open-source 2FA app for Android prioritizing security. It offers robust encryption, backups, and essential features missing from other authenticators.

What we love ❤️

  • Fully free and open-source with no in-app purchases or ads
  • Encrypts the vault using AES-256-GCM, protected by password or biometrics
  • Supports industry-standard HOTP and TOTP authentication algorithms
  • Allows importing codes from various other authenticator apps
  • Offers organization features like custom sorting, icons, and grouping
  • Provides export options for encrypted or plaintext backups
  • Includes automatic backups using Storage Access Framework

Worth noting 💡

  • Requires Android device for usage, no iOS version available
  • Some import options may require root access on the device
  • Lacks cloud sync capabilities

Best suited for privacy-conscious Android users who want full control over their 2FA setup. While it requires more manual management than cloud-based alternatives, this trade-off provides superior privacy and control over sensitive authentication data.
