Enable two-factor authentication for Docker Hub
Two-factor authentication adds an extra layer of security to your Docker Hub 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 Hub account.
You need a mobile phone with a time-based one-time password authenticator application installed. Common examples include Google Authenticator or Yubico Authenticator with a registered YubiKey.
Sign to your Docker Hub account.
Select your username and then from the drop-down menu, select Account Settings.
Select the Security tab and then select Enable Two-Factor Authentication. The next page reminds you to download an authenticator app.
Select Set up using an app. Your unique recovery code is sent to you.
Save your recovery code and store it somewhere safe. Your recovery code can be used to recover your account in the event you lose access to your authenticator app.
Select Next and then open your authenticator app. You can choose between scanning the QR code or entering a text code into your authenticator app.
Once you have linked your authenticator app, enter the six-digit code to in text field and then select Next.
Two-factor authentication is now enabled. The next time you sign in to your Docker Hub account, you will be asked for a security code.
