Android Studio can't login to GitHub

I have faced this problem too. Try using token to login.

Log in to github.com on the browser. Go to Settings -> Developer settings -> Personal access tokens. There you can create a new token and then, go back to Android Studio, select Enter Token at the login prompt.

I use "github.com" as host (not the whole clone url), and my github login and password and can login without any issues.

In host you only have to put 'http://github.com'

Nothing more
