Google Nest 2FA: How to Set Up an Authenticator App

nest.com Supported

Enable two-factor authentication on Google Nest to stop unauthorized logins. After setup, Google Nest asks for a rotating code from Authenticator App - Novaz in addition to your password.

A Google Nest account can control connected devices in your home, so 2FA keeps intruders out. Besides an authenticator app, Google Nest also offers SMS text codes, phone-call codes, a proprietary app and security keys. 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, Google Nest also supports hardware security keys.

2FA methods Google Nest supports

  • SMS text message
  • Phone call
  • Authenticator app (TOTP)
  • Proprietary app
  • Security key (U2F / WebAuthn)

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

  6. 6

    Save a way to recover your account.

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

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

How to recover your Google Nest account

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