Puzzlescript Plus requires a slightly different way to authenticate your GitHub account so I don't have to set up a server to handle it properly. Sorry! Here's how it works:

1) Go to the New Personal Access Token page on GitHub.
2) As the Note, enter Puzzlescript Plus (or anything you want, really).
3) For Scopes, make sure you ONLY check "gist". Leave the rest disabled, if you enable more it can become a security risk for your account.
4) Then, click "Generate token". On the next page, you'll be able to see the new personal access token. This code acts basically a password for your account, so don't share it anywhere but here! Copy it down here, press submit, and it should work!

Credits to Clément Sparrow for implementing this alternative Github authentication method!

PuzzleScript Plus has been authorized to save your game as a Gist on GitHub on your behalf from this browser. The token was saved, and if it was correct you can now share games. Open the editor and click SHARE to test it! If for some reason it does not work, click the button below and try the authorization procedure again.
