Nulab 2FA: How to Set Up an Authenticator App

nulab.com Supported

Nulab supports app-based two-factor authentication (2FA). Turning it on adds a second layer of protection, so a stolen password alone can't unlock your Nulab account.

A Nulab account carries private conversations, so keeping it secure with 2FA matters. Besides an authenticator app, Nulab also offers security keys and SMS text codes. An authenticator app (TOTP) is usually the best balance of security and convenience — and it's safer than SMS codes, which can be intercepted through SIM-swap attacks. For the strongest protection, Nulab also supports hardware security keys.

2FA methods Nulab supports

  • Security key (U2F / WebAuthn)
  • Authenticator app (TOTP)
  • SMS text message
  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 Nulab's QR code and generate your 6-digit sign-in codes.

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

  4. 4

    Scan the QR code with Authenticator App - Novaz.

    Open Authenticator App - Novaz, tap add, and point your camera at the QR code Nulab 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 Nulab account.

  6. 6

    Save a way to recover your account.

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

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

How to recover your Nulab account

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