Hi Ewan,
There could be several reasons why you are receiving an "Incorrect password or username" error message.
Here are a few possible causes and solutions:
Incorrect username or password: Please verify that you are entering the correct username and password for your GitHub account.
Using an outdated authentication method: GitHub no longer supports password-based authentication. It is recommended to use personal access tokens (PATs) or SSH keys instead. Generate a PAT in your GitHub account settings and use it as your password when prompted.
Firewall or proxy settings: If you are behind a firewall or using a proxy, it could interfere with the authentication process. Check your network settings or try using a different network to see if the issue persists.
I hope this helps!
