When the RapidIdentity MFA Client is installed, it can also be used with the UAC (User Access Control) by right-clicking an application to "Run as a different user".
You'll notice when using this feature that only one of the MFA methods will appear.
By default, it automatically brings up your most recently used authentication method. This feature is hardcoded and cannot be changed. You can still access your other methods by selecting "More choices", where you will be presented with all of your available authentication methods.
