GitHub logon failed with GCM

[ThomsonTan]

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)
• 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.
