MyGMC App will not connect Android phone unable to complete authorization
I figured it out. For those who are still having issues try to clear your cache from chrome and Microsoft Edge browsers and clear your device cache as well, then try it again. That should work.
Ok, so I fixed my issue. This may help someone else. I recently upgraded phones, and my new phone would not login. Same issue as in this thread. I fired up my old phone to see if it would still work there and it did, but i noticed it did not ask me for a password or authentication, it came right up to my profile. So i logged out of the app on the old phone, then tried on the new phone and the authentication went through this time. Even though the phone was powered off, OnStar was still somehow attached to that phone. So My problem is solved. Hope this will help someone else. Go to your PC or anything that you have logged into your OnStar with and see if your still logged in there, Hope this helps, CIAO!
This is a good point to bring up when having log-in/MFA troubles. Making sure that you're logged out on your other devices can prevent miscommunications related to authentication/verification when logging in on a new device. We appreciate your input on this matter.
