Manually Attaching Discord Profile

You can manually attach the Discord profile to the WordPress user by assigning a Discord ID.

If you go to your personal profile page in the WordPress admin panel and scroll down to see a Discord Data section, you will find connected Discord profile data and a button to re-connect a new one.

If, as the website administrator, you go to the same place on other user profiles, you will find an option to attach the Discord profile manually by saving the Discord user ID.

If you attach the wrong ID, another person can log in with this WordPress account. Also, a new account will be created when the correct person returns.

Here you can read more about finding the Discord user ID.
