Google OAuth2.0 allows users NOT in list of test users
Mar 23
I'm developing a webapp which allows users to log in with their Google accounts, using OAuth2.0. I've created an OAuth2.0 client ID, configured the OAuth consent screen with the Publishing status set to 'Testing', and added a test user.
The frontend of my app is built with React, and I'm using a package (react-google-login) to handle the flow. I can successfully sign in with the Google account I added as a test user, and retrieve the basic profile information needed.
The problem is I can also sign in with other Google accounts, which have not been added to the list of test users. I imagine that Google should simply not issue access tokens for accounts which are not in the list of test users.
I feel like I've misunderstood something about the OAuth process, or I have configured something incorrectly. I would appreciate if anyone had any pointers?
Thanks.

It is indeed bugged.
I was in the same spot as you, assuming I had misunderstood something. After reviewing my code over and over with no luck, I made a Stack Overflow post, in which I was advised to post to Google's bug tracking system. After doing some troubleshooting with Google they confirmed the bug, and they are now working to fix it (for a little while already).
I included this thread as an example when talking to Google. I meant to post an update here after getting in touch with them, but I forgot, sorry!

Your perspective belongs here.
