SafeAuthEntry

Offline 2FA authenticator (TOTP/HOTP) with an encrypted vault (AES-256-GCM) protected by a master password.

SafeAuthEntry generates two-step verification (2FA) codes right in Chrome, compatible with the TOTP (RFC 6238) and HOTP (RFC 4226) standards used by most websites. Private by default: all accounts stay only on your computer, encrypted with AES-256-GCM and protected by a master password (PBKDF2-SHA256, 600,000 iterations). The extension makes no network connections and collects no data. Features: - Add accounts by scanning the QR code on the open page, with the camera, from an image, or by typing the key. - Import accounts exported from other authenticators (standard `otpauth://` format and unencrypted exports). - Copy codes with one click, with a visual countdown. - Favorites, search, reordering and keyboard shortcuts. - Auto-lock when the extension is closed, when the computer screen is locked, and after inactivity. - Password-encrypted backup (`.safeauth` file). - Dark and light themes. - Interface in English, Portuguese and Spanish. Important: the master password cannot be recovered. Keep an encrypted backup in a safe place.
