GateKeeper is a mobile application that provides a six-digit one-time password, which you should provide in addition to your username and password to log into your Accounts opened with a Third Party Provider and to confirm your active operations that require authorization. The app can be used for multiple accounts. You can get an authorization code even if you do not have an Internet connection or mobile service.
The GateKeeper mobile app works only when paired with an Account. Once the application is set-up, it generates different authorization codes for each connected Account. The generated codes are unique for each of the accounts and are constantly changing.
The GateKeeper Mobile app is available for devices with operation systems iOS and Android.
