Set up two-step login with FIDO U2F

bitwarden supports two-step login via FIDO U2F. Any FIDO U2F certified device will work. We recommend a YubiKey.

Note

Due to platform limitations, FIDO U2F cannot be used on all bitwarden applications. You should enable another two-step login provider so that you can access your account when FIDO U2F cannot be used.

Supported platforms:

  • Web vault on a desktop/laptop with a U2F enabled browser (Chrome, Opera, Vivaldi, Brave, or Firefox with addon).
  • Browser extensions on Chrome, Opera, Vivaldi, or Brave.

Enable Two-step Login with FIDO U2F

Warning

Two-step login can permanently lock you out of your account. It is very important that you write down and keep your two-step login recovery code in a safe place in the event that you lose access to your FIDO U2F security key.

  1. Log in to the web vault at https://vault.bitwarden.com
  2. Click Settings on the sidebar. Click Two-step Login in the sub-menu that opens under Settings.
  3. Select the FIDO U2F Security Key option and then type in your master password to continue.
  4. Follow the instructions shown:
    • Plug the security key into your computer’s USB port.
    • If the security key has a button, touch it.

    You will receive a success message when your key has been properly read. Click the Try again button if it fails.

  5. Click the Enable button. A green alert will appear at the top stating that two-step login has been enabled.
  6. Click the Close button and confirm that the FIDO U2F Security Key option now shows as Enabled.

Test

  1. IMPORTANT: Ensure that you have copied down your two-step login recovery code in case something goes wrong.
  2. Log out of the bitwarden web vault.
  3. Log back into the bitwarden web vault. You should now be prompted with a FIDO U2F two-step login option. Insert your FIDO U2F security key (if it has a button, touch it) to complete logging in.
  4. Log out of and back in to any other bitwarden applications that you are using to confirm that two-step login via FIDO U2F is properly working. You will eventually be logged out automatically. If the application (or device) your are using does not support FIDO U2F you will be presented with other two-step login options that you have configured (if any).
