Everything is organized in one app so you can manage many accounts with clarity and speed.

Features

Offline one-time codes

Google Authenticator generates codes without internet or mobile service, so you can sign in on the go. The app supports time-based and counter-based codes that refresh on a short timer to keep access secure.

Secure cloud sync

When you sign in to your Google Account, Google Authenticator can sync your codes to your other devices. The app encrypts codes in transit and at rest, and this helps you avoid lockouts when changing or upgrading phones.

Quick setup and migration

You can add new accounts with a QR code or a setup key in seconds. Moreover, you can export selected accounts to a QR and import them on another device for a smooth migration with minimal downtime.

Manage many accounts with ease

Google Authenticator keeps multiple accounts in one place. You can search by name, edit labels for clarity, and reorder entries so the codes you use most are always at the top.

Privacy Screen protection

In Google Authenticator, you can add device protection that requires your PIN, pattern, or biometrics before viewing codes. Therefore, your codes stay hidden from casual glances until you authenticate.

Use local only or enable sync

Google Authenticator works without a Google Account for local-only storage. Also, you can enable sync later to back up codes and access them on all your devices when you need them most.

More about Google Authenticator

Offline reliability and encryption details

The app generates codes locally on your device, so sign-in works even when you have no signal. And when you choose to sync, Google Authenticator protects your codes with encryption both in transit and at rest to reduce exposure risks.

Choosing local only or cloud sync

Privacy-focused users can keep everything on a single phone with local-only mode. In addition, users who upgrade devices often may prefer sync to reduce the chance of account lockouts and to streamline device changes.

Google Authenticator for PC

There is no separate desktop app. You use the Google Authenticator app for Android to read the code on your phone while signing in on your PC. Many services also support passkeys or other second steps if you prefer an alternative.

Time accuracy matters

Google Authenticator relies on your device's system time. Therefore, you should keep automatic date and time enabled so codes match the services you use and avoid incorrect code errors.
