Bitwarden Authenticator App

Secure your accounts with trusted two-factor authentication

The free Bitwarden authenticator app is open source and generates time-based codes for multi-factor authentication, adding an extra security layer to protect your digital life.

Available free on iOS and Android.

Why Multi-Factor Authentication Matters

Multi-factor authentication (MFA) and two-factor authentication (2FA) provide critical protection beyond passwords alone. If a cyberattack were to occur , malicious actors could not access your account without the time-based verification code generated by our authenticator app.

Unlike SMS-based two-factor authentication, which can be intercepted, app-based authenticators like Bitwarden generate codes locally on your device, making them significantly more secure for protecting your sensitive accounts.

Generate two-factor authentication codes instantly

The Bitwarden Authenticator app generates time-based one-time passwords (TOTP) for any service that supports two-factor authentication. These 30-second rotating codes ensure your identity is verified, keeping your sensitive data protected from unauthorized access even if your password is compromised.

Understanding two-factor authentication

How two-factor authentication works

When you log in to a protected account, you'll enter your password first, then open your Bitwarden Authenticator app to get a 6-digit code that changes every 30 seconds.

This multi-factor authentication process ensures that even if your password is compromised, they can't access your account without physical access to your device.

Authenticator app vs. SMS two-factor authentication

While SMS-based 2FA is better than no protection, authenticator apps provide superior security:

  • No network dependency: Codes generate offline

  • SIM-swap protection: Codes aren't sent via vulnerable SMS

  • Faster access: Instant code generation without waiting for texts

  • International reliability: Works anywhere without roaming issues
