Currently, WPM is unable to pass the Google authentication used by both GSuite and custom services hosted in Google (GCP) using Google identity as means of authentication. The core issue is that Google (correctly) identifies the WPM login attempt as being automated, and throws a CAPTCHA that WPM is unable to pass.
the google auth mechanism (IAP) has a means of getting an oauth token programatic, as mentioned here: https://cloud.google.com/iap/docs/authentication-howto
To have WPM support this would probably be the only feasible way of using WPM to check services hosted behind Google auth.
