      How do I set up two-factor authentication (2FA)?

      Use a passkey or authentication app to secure your account.

      To maximize your account's security, we recommend that you set up two-factor authentication. This ensures that even if your account password is compromised, an attacker still needs a second piece of information to access your account.

      Tip: If you lost your passkey or need to reset your 2FA for any reason, you can reset your 2FA using your email.

      Unchained supports multiple authentication methods:

      • Passkeys (recommended): This security protocol requires a physical device, like a phone, computer, or Yubikey, to be present when you sign in. Passkeys are phish-resistant and account-takeover-resistant, and they are our recommended 2FA option. You can sync multiple passkeys to your account.
      • Time based One-Time Passwords (TOTP): A smartphone authentication app like Google Authenticator generates codes you will use to sign in.

      How to enable a passkey on your account:

      1. Navigate to the Security Tab of the User Info page. 
      2. Click Add a passkey from the Passkey section. 
      3. A window will open up allowing you to initiate the passkey registration process. Click Next.
         
        • Using phone/tablet: Scan the QR code shown on screen. This will open up the passkey setup flow on your device. Follow the instructions on your device. Complete the steps on your device.
        • Using a hardware device (Yubikey): Plug in your device. You’ll be requested to touch the device to register it as a passkey. If it has a pin, you’ll be prompted to enter the pin on screen.
      4. Success! Your passkey will appear in your passkeys section. 

      Note: If you add a Yubikey as a passkey, you cannot use that device to access your account on the Unchained iOS app. We recommend that you also add your iPhone as a passkey for uninterrupted mobile access.

      How to enable TOTP codes on your account:

      1. Download an authentication app. There are several available, but apps we recommend include:
      2. Navigate to the Security Tab of the User Info page.
      3. Click Enable TOTP.
      4. Scan the QR code using your TOTP app. Your app will add a new item labeled "Unchained".
      5. Enter the six numbers shown on your authentication app and click Enable 2FA.
      6. Success! You will now be prompted to enter your 2FA code when signing in.

      Note: If you have both TOTP enabled and a passkey on your account, the passkey overrides the TOTP option.
