## What is Two factor authenticator?

We 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 our app on your phone.

The verification code can be generated by our app on your phone, even if you don't have a network or cellular connection.

• Sync your Authenticator codes to your accounts and across your devices. 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.


To use app with accounts, you need to enable 2-Step Verification on your accounts.
