Attempting to login via Google, Facebook, or Twitch will only work if you have connected your FANDOM account to your account from the other platform. Users can do this by either using the external account to initiate the account creation process or by linking the accounts after creation via Special:Preferences.

Have you tried using the "forgot password" option? If you use this, you should get an email allowing you to reset your password. If your account is linked to one of the external platforms, you will need to re-link it after regaining access to your account.
