Yahoo 2FA: How to Set Up an Authenticator App
Your Yahoo account is the key to Yahoo Mail and your other Yahoo services, so it deserves more than a password. Yahoo calls the feature 2-step verification and offers an "Authenticator app" method, which works with Authenticator App - Novaz. Once it's on, Yahoo asks for a code from the app when you sign in from a new device or browser.
Your Yahoo inbox is the master key to your other accounts — attackers use it to reset passwords everywhere. Besides an authenticator app, Yahoo also offers SMS text codes, phone-call codes 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, Yahoo also supports hardware security keys.
2FA methods Yahoo supports
- SMS text message
- Phone call
- Authenticator app (TOTP)
- Security key (U2F / WebAuthn)
Before you start
- Your Yahoo ID and password: if you don't see the option to turn on 2-step verification, create a password first
- At least 2 recovery methods (a recovery phone number or email address) on your account, because the "Authenticator app" option only appears once you have them
- Account Key turned off, if you use it to sign in without a password: Yahoo requires you to disable it before enabling 2-step verification
- Authenticator App - Novaz installed on your iPhone or iPad
- Your Yahoo Account Security page open on a computer, so the QR code is on a different screen from your phone

Save a way to recover your account
If Yahoo offers backup or recovery codes, download them or write them down and store them somewhere safe. They are how you get back into your account if you ever lose your phone. If it doesn't, check how Yahoo recovers accounts before you need it.
If something goes wrong
- There's no "Authenticator app" option: you need at least 2 recovery methods. On the Account Security page, under "Ways of signing in", click "Add email" or "Add phone number", click "Next" and follow the prompts to verify it.
- There's no option to enable 2-step verification at all: make sure your account has a password. If you use Account Key, go to the Account Security page, click "Turn off Account Key", then "Turn off" and "Turn off" again to confirm.
- Yahoo rejects the code: make sure your iPhone sets its date and time automatically (Settings > General > Date & Time), then enter the newest code.
- Your account is locked after too many failed sign-ins: Yahoo unlocks it automatically after 12 hours, or you can regain access right away with the Sign-in Helper at login.yahoo.com/forgot.
- A third-party email app can't sign in to Yahoo Mail: Yahoo's 2-step verification help points you to generating an app password for it.

How to recover your Yahoo account
Yahoo's help pages for 2-step verification don't describe backup codes for the authenticator app. What they do describe is recovery info: recovery email addresses and phone numbers help you reset your password and confirm your identity when you sign in from a new place, and Yahoo requires at least 2 of them before it offers the "Authenticator app" option. If you can't sign in, Yahoo sends you to the Sign-in Helper at login.yahoo.com/forgot, where you enter your recovery phone number or email address and follow the instructions. Keep that information current under "Ways of signing in" on the Account Security page: Yahoo warns that if your recovery info is wrong or inaccessible, you may not be able to regain access to your account.
