It works as a 2FA code generator: it makes the one-time codes that websites and apps ask for at sign-in when an account is protected with an authenticator app (TOTP). The codes are made right on your phone, so a stolen password alone does not open your account.

Works with Microsoft, Google, Facebook, Instagram, Amazon, Binance, Coinbase, GitHub and other services when they offer TOTP setup

ADD A 2FA ACCOUNT IN SECONDS
• Turn on 2-step verification on a website or app and scan its QR code. Authenticator then shows a verification code you can enter when you sign in.
• Or choose a picture of the QR code, paste the setup link, or type the key.
• Works with websites and apps that support time-based one-time passwords (TOTP).
• 6- and 8-digit codes, 30- and 60-second periods.
• Microsoft accounts too, including Outlook, Microsoft 365, Azure and Entra ID sign-ins, where the account supports third-party TOTP codes.

MOVE TO A NEW PHONE WITHOUT LOSING YOUR 2FA CODES
• Import your time-based (TOTP) accounts from Google Authenticator: scan the QR codes it shows under Transfer accounts.
• Encrypted backup and sync through your Google Drive. Every copy is encrypted with a password only you know.
• Save an encrypted backup file with Premium; restore everything from it on your new phone.
• Deleted an account by mistake? Restore it from Recently deleted within 7 days of deletion.

LOCKED AND PRIVATE
• Lock the authenticator app with a PIN, your fingerprint or your phone's screen lock.
• Codes are made on your phone and work offline. No sign-up, no account with us.
• Screenshots and screen recordings are blocked where your codes are shown.

ORGANIZED YOUR WAY
• Folders for work and personal accounts, search and your own order.
• Icons for more than 3,000 services, or the standard icon in a color you pick.

HOW TWO FACTOR AUTHENTICATION HELPS
With multi-factor authentication (MFA) through an authenticator app, signing in takes your password and a one-time password (OTP) from your phone. The code changes at the interval set by the account, often every 30 or 60 seconds, so a password alone is not enough. Turn on 2FA wherever a website or app offers it, then add the account here.

FREE TO USE, PREMIUM FOR NO WAITING
Authenticator is free to use: codes and most features open after a short wait. Premium is a weekly subscription that opens every code and feature right away. Cancel anytime in Google Play.
