Problems with `git push`

If you received:

```shell
$ git push
remote: Invalid username or password.
fatal: Authentication failed for 'https://github.com/githubteacher/automatic-succotash.git/'
```

This is caused by the Windows Credential Manager, known as `manager`. You can unset it with:

```shell
$ git config --system --unset credential.helper
```

Then try your `git push` again. After entering your username and password, it should work :white_check_mark:

```shell
$ git push
Username for 'https://github.com': githubteacher
