About this app

Signing in shouldn't mean hunting for a code. 2FA Guard Authenticator keeps your two-factor authentication codes in one place, ready when you need them. Open the app, find your account and tap to copy.

It generates time-based one-time passwords (TOTP) on your Android phone, even without Wi-Fi or mobile data. Use it with services that support authenticator-app verification.

GET SET UP WITH A QR CODE
Turn on two-factor authentication in your service's security settings, then scan its setup QR code. Prefer to enter the setup key yourself? You can do that too. Review the account details, save them and enter your first code in the service to finish setup.

FIND YOUR CODE WITHOUT THE SCROLLING
Search by service or account name, copy a code with a tap and see how long it has left before it refreshes. Rename entries so they're easy to recognise, or remove accounts you no longer need.

GENERATE CODES OFFLINE
Your phone generates the codes locally. You don't need an internet connection to open the app and get a code, though the service you're signing in to may still need one.

KEEP SETUP KEYS ON YOUR PHONE
Secret keys are encrypted with AES-256-GCM using Android Keystore. QR scanning happens on your device. There's no account to create with us, no advertising and no analytics SDK.

CHOOSE A LOOK THAT SUITS YOU
Use light mode, dark mode or follow your system setting. On supported devices, dynamic colours let the app match your wallpaper.

Screen security is on by default to block screenshots and hide app contents in the recent-apps view. You can change it in Settings. It isn't a PIN or biometric app lock.

BEFORE YOU SWITCH PHONES
The app doesn't offer cloud sync, account export or recovery. The account database is excluded from Android backup and device transfer. Keep the recovery codes provided by each service somewhere safe, and make sure you can sign in another way before changing phones, clearing app storage or uninstalling.

COMPATIBILITY
Supports services that provide standard TOTP setup keys or QR codes. Counter-based HOTP codes and bulk account-transfer QR codes aren't supported. Authenticator generates verification codes; it doesn't replace your account passwords or turn on two-factor authentication for you.

Free to use, with no ads.
