The sentence of its App Store description that best says what it is, picked by Jev. The developer's own words.Google Authenticator adds an extra layer of security to your online accounts by adding a second step of verification when you sign in. This means that in addition to your password, you'll also need to enter a code that is generated by the Google Authenticator app on your phone.
The verification code can be generated by the Google Authenticator app on your phone, even if you don't have a network or cellular connection.

• Set up your Authenticator accounts automatically with a QR code. This is quick and easy, and it helps to ensure that your codes are set up correctly.
• Support for multiple accounts. You can use the Authenticator app to manage multiple accounts, so you don't have to switch between apps every time you need to sign in.
• Support for time-based and counter-based code generation. You can choose the type of code generation that best suits your needs.
• Transfer accounts between devices with a QR code. This is a convenient way to move your accounts to a new device.
