Download and install the Google Authenticator app from the Apple Store (in order to use Google Authenticator on iPhone, iPod Touch or iPad, you must have iOS 13.0 or later).
Open the app and click "Start” and then “Create your first account”.
When the account "UniVR_MFA\XXXX" appears, click "Add account". The first TOTP code associated with the newly created account will then appear.
How to generate TOTP codes for authentication
Open the App
Select the Univr MFA account: this will display the TOTP code to be used (the icon on the right indicates the time remaining until the TOTP code expires).
