Git push “fatal: Authentication failed ”

问题原因

• 之前设置了两步验证

 If you enabled two-factor authentication in your Github account you won't be able to push via HTTPS using your accounts password. Instead you need to generate a personal access token. This can be done in the application settings of your Github account. Using this token as your password should allow you to push to your remote repository via HTTPS. Use your username as usual.

解决方法

• 更新分支

git remote -v 
git remote remove origin 
git remote add origin git@github.com:user/repo.git
