Two-factor authentication adds an extra layer of security to your Docker account by requiring a unique security code when you sign in to your account. The security code is required in addition to your password.

When you enable two-factor authentication, you are also provided with a recovery code. Each recovery code is unique and specific to your account. You can use this code to recover your account in case you lose access to your authenticator app. See Recover your Docker account.

Prerequisites#

You need a mobile phone with a time-based one-time password (TOTP) authenticator application installed. Common examples include Google Authenticator or Yubico Authenticator with a registered YubiKey.

Enable two-factor authentication#

1. Sign in to your Docker account.
2. Select your avatar and then from the drop-down menu, select Account settings.
3. Navigate to the Security section, then select Two-factor authentication.
4. Enter your account password, then select Confirm.
5. Save your recovery code and store it somewhere safe. You can use your recovery code to recover your account in the event you lose access to your authenticator app.
6. Use a TOTP mobile app to scan the QR code or enter the text code.
7. Once you've linked your authenticator app, enter the six-digit code in the text-field.
8. Select Enable 2FA.

Two-factor authentication is now enabled. The next time you sign in to your Docker account, you will need to enter a security code.
