Substack 2FA: How to Set Up an Authenticator App

substack.com Supported

Protect your Substack account with two-factor authentication (2FA). Once enabled, signing in also requires a one-time code from your authenticator app — not just your password.

A hijacked Substack account can be used to impersonate you and scam your contacts, so 2FA matters. Substack secures sign-ins with an authenticator app — set it up once and you're protected on every login.

2FA methods Substack 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 Substack's QR code and generate your 6-digit sign-in codes.

    Download on the App Store
  2. 2

    Sign in to Substack and open your Substack 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 Substack 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 Substack account.

  6. 6

    Save a way to recover your account.

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

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

How to recover your Substack account

If you lose access to your authenticator and Substack 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 Substack doesn't, or you didn't save them, use Substack's account-recovery or support process (or ask your admin, for a work account) to get back in.
