I was trying to clone a repo and was facing this issue, I tried removing all git related credentials from windows credentials manager after that while trying to clone git was asking me for my credentials and failing with error invalid username or password. This was happening because the repo I was trying to clone was under an organization on github and that organization had two factor auth enabled and git bash probably do not know how to handle 2fa. So I generated a token from https://github.com/settings/tokens and used the github token instead of password while trying to clone the repo and that worked.

我有同样的问题，并发现我在~/中有另一个密钥文件。ssh到不同的GitHub存储库。不知怎么的，它代替了新的。

试试这个，对我很管用。

git remote rm origin
git remote add origin https://github.com/your-username/{{project-name}}.git
