最近，我在线更改了我唯一的Github帐户的密码。从那时起，每当我在本地机器上使用git做任何事情时，它都会一直询问我的用户名和密码。我看了How do I update the password for Git?和https://help.github.com/articles/updating-your-github-access-credentials/。
问题Git keeps prompting me for password和git: osxkeychain credential helper silently fails to remember username/password与我的相似，只是我没有使用SSH（或者如果git使用ssh我不知道它。我的.ssh目录中不包含任何关于Github的内容）。
我以前在Keychain应用程序中有一个github项目。由于事情不起作用，我选择删除 它，现在当我在某些github操作中输入我的用户名和密码时，没有自动创建新项目。
尝试git config --global credential.helper osxkeychain会产生以下错误
$ git config --global credential.helper osxkeychain
warning: credential.helper has multiple values
error: cannot overwrite multiple values with a single value
Use a regexp, --add or --replace-all to change credential.helper.
以下是git config -l的输出：
git config -l
credential.helper=osxkeychain
user.name=ewan-delanoy
user.email=<my e-mail here>
push.default=simple
credential.helper=osxkeychain

您只需编辑全局文件即可只留下一个条目：
git config --global --edit
同时检查 该设置的设置位置：
git config -l --show-origin
然后delete your old credentials stored in it。
