Protect your accounts with a private TOTP authenticator app for iPhone. Generate secure 2FA/MFA codes offline, lock the app with Face ID or Touch ID, and keep your credentials safe—all in one intuitive tool.

Meet your new authentication app that gives every account a second layer of security. Your password is only half the lock. Authenticator is the other half: it generates a one-time code that expires in seconds and can’t be reused. From email to banking, that’s how you prove it’s really you.

With Authenticator App, you can:
• Keep hackers away—a stolen password alone won’t unlock your accounts.
• Sign in stress-free—your codes are ready whenever you need them.
• Stay organized—codes and passwords are kept safe in one place.

Everything you need, built in:

GENERATE SECURE 2FA CODES
Create OTP codes—based on the RFC 6238 open standard—for any service that uses multi-factor authentication. Codes refresh every 30 seconds and warn you before they expire, making sure you can always authenticate with a valid one.

ADD ACCOUNTS QUICKLY
Set up accounts by scanning a QR code or entering a secret key manually. You can also save backup codes, keeping your accounts accessible even if your phone is lost or stolen.

STORE YOUR PASSWORDS SAFELY
Unlike most authenticator apps that only handle MFA codes, Authenticator App keeps your passwords and MFA codes together in one secure place. No more juggling separate apps or resetting passwords you can't remember.

GET CODES ON APPLE WATCH
Check your latest authentication codes right from your Apple Watch, then copy and paste them on your Mac or other devices.

AUTOFILL YOUR PASSWORDS
Use saved passwords to autofill login details on websites and in other apps, so you can sign in faster.

CHECK CODES ON YOUR HOME SCREEN
Choose from three widget styles and see your codes without even opening the app. Save time when signing in and skip a small but constant chore.

FIND CODES INSTANTLY
Managing a lot of accounts? Type the name of any service and its code appears right away, so you don’t have to scroll through a long list when you’re in a hurry.

LOCK YOUR CODES & STAY OFFLINE
Protect the app with Face ID or Touch ID so no one can see your codes even on an unlocked phone. The app works offline—an internet connection is only required for automatic backups.

RESTORE ON ANY DEVICE
Your codes are backed up safely through Apple’s Keychain, never leaving Apple’s secure system. Switch to a new phone, and everything restores automatically.

HOW TO GET STARTED
• Turn on 2-factor authentication for the account you want to protect.
• In the Authenticator App, scan the QR code or enter a secret key manually.
• Your code appears instantly—enter it on the login screen to finish signing in.
• New to MFA? A built-in guide shows where to find 2FA settings for popular services.
