Aegis Authenticator is a free, open-source two-factor authentication (2FA) app for Android that provides secure, offline management of one-time passwords (TOTPs). It’s designed as a privacy-respecting alternative to proprietary authenticators like Google Authenticator or Authy, offering strong local encryption and backup options without requiring an online account or cloud storage. Aegis gives users complete control over their 2FA tokens, aligning with ethical principles of data ownership, transparency, and user autonomy.
