Free Bitwarden Authenticator
The free Bitwarden Authenticator app is open-source and generates time-based codes for multi-factor authentication, adding an extra layer of security 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 would not be able to 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.
Enable multi-factor authentication – Strong passwords aren’t enough. Use Bitwarden Authenticator to enable multi-factor authentication across all your online accounts and applications. The Bitwarden Authenticator app is open-source and provides enterprise-grade security with the transparency and trust that come from publicly audited code.
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 – When you log in to a protected account, you’ll enter your password first, then open your Bitwarden Authenticator app to receive 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
Complete security with Bitwarden Password Manager integration – While Bitwarden Authenticator works perfectly as an end-to-end encrypted standalone app, it pairs seamlessly with Bitwarden Password Manager for comprehensive account security. The integration enables access to time-based one-time passwords from either application, Bitwarden Authenticator or Bitwarden Password Manager, reducing the need to manage codes across different apps.
Bitwarden Password Manager also includes built-in TOTP generation as a premium feature, allowing you to manage both passwords and authentication codes in one secure, encrypted vault.
