Two-Factor Authentication for NodeBB

In addition to regular authentication via username/password or SSO, a second layer of security can be configured, permitting access only if:

• A time-based one-time password is supplied, typically generated/stored on a mobile device, or
• A hardware token is activated, such as a Yubikey or other similar product

The Two-Factor Authentication plugin will expose this feature to end-users, allowing them to configure their devices and enabling this enhanced security on their account.

Version History

• v7.x
  • Logged-in users who have not passed the second-factor are now treated as guests. Prior to this, they were considered logged in, but were not able to physically navigate away from the 2FA challenge.
  • v7.0.2 to v7.2.2 (inclusive) allowed routes mounted to /api/v3 to not be protected by this plugin. This allowed automated processes to interact via API with 2FA-protected accounts without being challenged for a second factor. As of v7.3.0, this exception was removed as best-practice for security.
• v6.x
  • NodeBB v3.x compatibility
• v5.x
  • Allows for multiple concurrent second factors (e.g. TOTP and WebAuthn).
  • The backup code is now considered a second factor, although it is still recommended to be generated when setting up TOTP/Authn
• v4.x
  • NodeBB v2.x compatibility
• v3.x
  • Introduces hardware key support via WebAuthn.
  • This version is fully backwards compatible with v2.x. The major version bump was merely due to the introduction of the new functionality

Caveats

• Due to browser limitations, the hardware key on mobile devices (especially Android devices) may not be supported. For more information on which devices are and are not supported, please consult this chart
