Google Authenticator for iPhone

Strengthening account protection

Google Authenticator is a compact tool that adds an extra verification step to your sign-ins. Instead of relying solely on a password, it produces one-time passcodes that change regularly or after each use, making unauthorized access much harder.

Easy setup and device moves

Setting up a new account is simple: scan a QR image presented by the service and the account is added instantly. Moving your authentication entries to another phone is equally straightforward — you can export and import accounts using QR codes so you don’t lose access when upgrading devices.

Sync and recovery options

For added peace of mind, the app can synchronize codes with your Google account so codes are available on multiple devices. This synchronization acts as a safeguard if a device is lost or replaced, letting you restore access without recreating every entry.

Offline reliability and multi-account management

Because codes are produced locally on the device, they work without an internet connection — useful when you have poor reception or are traveling. The app also supports storing many accounts in one place, so you can handle authentication for several services from the same interface.
