Your fan game got hyperhimes discord account deleted
While I did not watch the video, I was told it was an issue with Discord 2FA, 3baked only caused HyperHimes to log out, which he then could not log back in.
3baked Discord login is essentially just Discord OAuth2, you login via Discord, and a code is sent from Discord to 3baked which allows it to access basic account details (username, id). It is just a secure means of logging in, 3baked cannot access anything more, and tells you what it can access while logging in.
