Stop reaching for your phone every time you log in. 2! Authenticator brings secure, Time-based One-Time Passwords (TOTP) directly to your desktop browser. Fully compatible with the export features of major mobile authenticator apps, this extension keeps you in your workflow while maintaining top-tier security.
