Which Version of GCM are you using ? 1.20.0 From a command prompt, run git credential-manager version and paste the output.

Which service are you trying to connect to

• [ ] Azure DevOps
• [ ] Azure DevOps Server (TFS/on-prem)
• [x] GitHub
• [ ] GitHub Enterprise
• [ ] Bitbucket
• [ ] Other? - please describe;

If AzureDevops Hosted describe your url

• [ ] dev.azure.com/org
• [ ] org.visualstudio.com

If you're using Azure DevOps, can you access the repository in the browser via the same URL?

• [ ] Yes
• [ ] No, I get a permission error.
• [ ] No, for a different reason:

If you're using Azure DevOps, and the account picker shows more than one identity as you authenticate, check that you selected the same one that has access on the web.

• [ ] I only see one identity.
• [ ] I checked each and none worked.

Expected behavior Cannot logon to with my account name/password/pass code. It happened many times, and when it happened, the login may succeed after multiple retries (like more than 10 times of retries).

git push
Logon failed, use ctrl+c to cancel basic credential prompt.

Actual behavior Repeated show login and pass code dialog, and "logon failed" message to console.

Set the env variables GCM_TRACE=1 and GIT_TRACE=1 and run your git command. Redact any private information and attach the log gcm_trace.txt

I have the same problem. Extract form the logs:

Logins are coming from a Password Manager and work successfully after a logout | login in a Web browser.

@springcomp for my case, I have 2 factors authentication enabled. It worked if I log in with Github PAT instead of password.
