虽然前面的回复提供了各种解决方案，但我发现其中最简单的一个是将用户名添加到存储库的URL中

git remote add origin https://your-username@github.com/your-username/repository-name.git

如果你已经定义了存储库(没有添加用户名)，你可以按照以下方式更新它:

git remote set-url origin https://your-username@github.com/your-username/respository-name.git

当推送到远程存储库时，git不会从凭据助手中提取任何其他现有存储库的凭据，而是会询问用户/存储库在URL中定义的特定密码。

一般来说，我会不惜一切代价避免使用您的帐户密码，而是使用个人访问令牌。登录github，选择，

Settings > Developer Settings > Personal Access Tokens > Generate new token

只要确保在定义令牌范围时选中repo，并在要求输入密码时输入令牌(而不是您的个人密码)。

操作系统

使用VS Code和一个没有密码的密钥:

removed eval "$(ssh-agent -s)" line from my ~/.zshrc file to stop running it in the background (first step on Github's Generating a new SSH key article) verified my .ssh/config entry for *.github.com did not have a UseKeychain line used simply ssh-add ~/.ssh/id_ed25519 with NO --apple-use-keychain on VS Code "Git: Add remote..." allowed/authorized my Github account connection (you don't really need to add a remote) applies a new "vscodevscode.github-authentication" entry in Mac's Keychain Access app closed all shells and VS Code, restarted and the repo is now always found

在我们的案例中，这只是一个在github中授予写权的案例。最初用户只有读权限，它给出了这个错误。

在我的情况下，上述解决方案都不起作用。

我通过将remote.origin.url从https切换到ssh来解决这个问题:

验证git配置:

git config --list

应该是这样:

...
remote.origin.url=https://github.com/ORG/repo-name.git
...

使用SSH更新remote.origin.url:

git remote set-url origin git@github.com:ORG/repo-name.git

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.

我遇到了同样的问题，但是当我发现我已经从另一个帐户创建了存储库，并试图从另一个帐户推送代码时。这就是现在我只需要给访问另一个帐户和问题解决。你会发现从
