## What is G Authenticator App?

Need a faster way to manage 2FA codes without switching between messages? Set up your accounts with QR scanning, generate MFA, OTP, and TOTP verification codes, and keep your authentication codes organized in one place.

Scan, save, and access your verification codes whenever you need them.

2FA & MFA Codes for Secure Sign-Ins

Add an extra verification step to accounts that support two-factor or multi-factor authentication.

Once an account is added, the app generates the current verification code directly on your device. When a service asks for a 2FA or MFA code, open the app, find the account, and enter the current code.

No need to wait for an SMS when authenticator-based verification is supported.

Fast Setup with QR Scanner

Adding an account is simple. Open the built-in QR scanner and scan the authentication QR code provided by the service.


OTP & TOTP Code Generator

Generate OTP and TOTP verification codes for compatible services. Codes refresh automatically at regular intervals, giving you the current code whenever authentication is required.

Use the authenticator with supported email accounts, work tools, shopping services, social platforms, payment services, and more.

Manage Multiple Accounts

Keep authentication codes for multiple accounts organized in one place.

Add accounts, rename entries, update details, and remove codes you no longer need. Whether you use the app for personal accounts, work accounts, or both, your verification codes remain easy to find.

Offline Authentication Codes

Access your saved authentication codes even without an internet connection.

Codes are generated directly on your device, making them available when your connection is weak, you are traveling, or SMS verification is not available.

App Lock for Extra Privacy

Protect access to your authentication codes with Face ID, Touch ID, or a PIN.

Auto-lock can automatically secure the app when you are no longer using it, helping keep your 2FA codes, MFA codes, and account information private.

Password Storage & Private Browsing

Keep login credentials organized with built-in password storage. Save account details and quickly copy them when needed.

The app also includes a private browser for opening websites and login pages without storing browsing history, cookies, or logs inside the app.
