How to install Google Authenticator?

The Google Authenticator app is used to generate two-factor authentication codes on your mobile device.

Two-factor authentication ensures greater protection for your account: to log into your account, a verification code will be required in addition to your password.

The Google Authenticator app can only be activated once two-factor authentication is enabled.

Google Authenticator is compatible with iPhone, iPod Touch, and iPad with iOS 5.0 or later. You can set up the app with the help of a QR code on the iPhone 3G or newer devices.

The Google Authenticator app is compatible with devices running Android 2.1 or later.
