I haven't got what to enter in fields **Username for** and **Password fo**r after the command **git push heroku master**:

```
C:\code2015>git push heroku master
Username for 'https://git.heroku.com': nemo
Password for 'https://nemo@git.heroku.com':
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/http-git#authentication
fatal: Authentication failed for 'https://git.heroku.com/django-blog.git/'

```

I have read documents, but do not still understand.

```
