App doesn't work if we change the OAuth Client ID

[Amissan]

Hi community,

I had generated an client ID using my personal google account to code the google login in my app, but the login is not working if I use otheur acounts even if I added them to the test list of OAuth consent screen  I had also generated an other client ID using an other account but it doesn't work, the google login in my app works only with one client ID and one account , my workmate tried to genarate a client ID using his account and still having the same issue.

I need to delever my work and make the google login in my app working for other acounts and using the client ID of the company, but it's not accepting other client IDs.

Thank you.

Do you mean that AppA and its Google authentication works with your client but not with your Google account? Meaning.. the client can open the app with their Google account, but you can't?
