Github Authentication failed（身份验

昨晚心血来潮改了个git的用户名，改完之后今早晨发现桌面客户端就出问题了。提示以下问题。

Authentication failed. You may not have permission to access the repository or the repository may have been archived. Open options and verify that you’re signed in with an account that has permission to access this repository.

也就是说身份验证失败。 您可能没有访问存储库的权限，或者存储库可能已被存档。打开选项并验证您是否注册了具有访问此存储库权限的帐户。
　　解决方法很简单，如果是GitHub Desktop，退出直接登录就好
