(Azure DevOps only) What format is your remote URL?

None

Can you access the remote repository directly in the browser?

Yes, I can access the repository

Expected behavior

I am able to access the Github repos and clone them when I set the GCM with plaintext. But by mistake if I try to access a repo for which I don't have access, then I get multple popups for giving the credentials, whereas I had already set and saved it in plaintext. When I check the details after that I see that the credentials are already deleted from the saved space. If I try to access an unauthorized repo, then it should only show that you are not authorized and it should not flush out the details stored.

Please help here

Start by reproducing the issue on Linux/RHEL 8 with Git Credential Manager 2.6.1, GitHub, and plaintext credential storage, using an unauthorized repository. Trace the authentication failure and credential-removal path; done means an unauthorized access attempt reports the failure without deleting valid stored credentials, while existing repository access continues to work.
