Once switched on, then every time, one of your users attempts to login to your Ongage account, they will be displayed a 2-Factor login form:
If you don’t already have, then you will need to download to your mobile phone: Google Authenticator, Authy Authenticator or any other Authenticator app out there. These apps are available for iOS and Android.
Then with one of the authenticators, scan the QR code and type in the 6 digit code (this code changes every 15 seconds). You will only need to do this step once.
From that point on every time you login, simply open the Authenticator app on your mobile phone, and type in the current code as it is displayed in the app.
Note: should you change or lose your phone, you will need to rescan the QR code. Resetting your password also resets the QR code as well.
