You've indicated that the URL that you're using is:
https://xxxxx@github.com/hello/folder.git
You've put your username in the URL. The xxxxx
portion of the URL is the username that you want to use for authentication. Since you've already provided it, Git will not prompt you for it. It will, however, prompt you for the password (though you could have included that in the URL as well, with the form https://xxxxx:password@github.com/hello/folder.git
).
If you want to be prompted for both username and password, simply remove it from the URL:
https://github.com/hello/folder.git
