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.

请在下面找到Windows的工作解决方案:

从“开始”菜单打开“控制面板”。 选择用户帐户。 选择“凭据管理器”。 点击“管理Windows凭证”。 删除所有与Git或GitHub相关的凭证。 一旦你删除了所有，然后尝试再次克隆。

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。

有时ssh凭证是安装在你的电脑上与github回购通信。 当你设置新的repo:如果你添加了https格式的origin，你的git凭证管理器不能找出repo。

检查产地格式

git remote -v

https格式的来源

origin  https://github.com/username/repo_name.git

ssh格式的原点

origin git@github.com:username/repo_name.git

删除https格式的origin

git remote remove origin

添加ssh格式的origin

git remote add origin git@github.com:username/repo_name.git

Linux用户:

Git远程rm来源

git远程添加origin https://GITHUB_USERNAME:PERSONAL_ACCESS_TOKEN@github.com/username/reponame.git

生成新令牌

执行git远程更新对我来说很有效。
