Question

git

Can't git push heroku master
Initially, it asked for username and password from GitHib , but after I entered the wrong username and password, errors started:
remote: ! WARNING:
remote: ! Do not authenticate with username and password using git.
remote: ! Run `heroku login` to update your credentials, then retry the git command.
remote: ! See documentation for details: https://devcenter.heroku.com/articles/git#http-git...
I looked at the documentation, nothing helped, did heroku login, unsuccessfully...
Help!
