This way, you can always access them even if you lose your phone. • 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.
