Docker 2FA: How to Set Up an Authenticator App

docker.com Supported

Docker lets you secure your account with an authenticator app. With 2FA on, each login needs a fresh 6-digit code, keeping your Docker account safe even if your password leaks.

A Docker account can expose source code, deploy keys, and infrastructure — prime targets for attackers. Docker secures sign-ins with an authenticator app — set it up once and you're protected on every login.

2FA methods Docker supports

  • Authenticator app (TOTP)
  1. 1

    Download Authenticator App - Novaz

    Install Authenticator App - Novaz from the App Store on your iPhone or iPad and open it — you'll use it to scan Docker's QR code and generate your 6-digit sign-in codes.

    Download on the App Store
  2. 2

    Sign in to Docker and open your Docker account security settings.

  3. 3

    Turn on two-factor authentication and choose the authenticator-app option.

    Look for "Authenticator app", "Authentication app", or "TOTP" rather than SMS.

  4. 4

    Scan the QR code with Authenticator App - Novaz.

    Open Authenticator App - Novaz, tap add, and point your camera at the QR code Docker displays. Can't scan? Enter the setup key manually instead.

  5. 5

    Enter the 6-digit code to confirm.

    Type the code Authenticator App - Novaz generates to verify and link your Docker account.

  6. 6

    Save a way to recover your account.

    If Docker shows backup or recovery codes, store them somewhere safe, away from your phone. If it doesn't, check how Docker recovers accounts (support, an admin, or another sign-in method) before you need it.

Menu names on Docker can change — the official Docker 2FA documentation ↗ always has the exact, current path.

How to recover your Docker account

If you lose access to your authenticator and Docker gave you backup or recovery codes when you turned on 2FA, sign in with one of them; keep them somewhere safe, away from your phone. Not every service issues codes. If Docker doesn't, or you didn't save them, use Docker's account-recovery or support process (or ask your admin, for a work account) to get back in.
