Authenticator is an elegant, open-source two-factor authentication app that supports the Time-based One-Time Password (TOTP) algorithm. It offers multiple convenient methods to set up your accounts: • Scan a QR Code. • Read from a QR Code image. • Import from a file. • Manual entry. The app features an beautiful “Account Details” page that displays each account along with its QR Code. You can view or copy this information at any time. Authenticator also provides several easy ways to export all your accounts: • Export key URIs to the clipboard. • Export key URIs as plain text. • Export key URIs as a TXT file. • Export key URIs as QR Code images. Authenticator always remains offline and never connects to any networks. It does not track any data or collect any personal information. Just works as it should be. Authenticator is fully open source on GitHub: https://github.com/bingzheung/authenticator
