How can I unlink my Apple ID from my discord account?

Hello Glacier70,

If this is an app/service that you're using 'Sign In with Apple' on, then this page can help provide info on managing that: Manage the apps that you use with Sign in with Apple - Apple Support

To see a list of the apps that you're currently using with Sign in with Apple and manage your preferences for each one, go to Apple ID settings on your device or sign in to your Apple ID account page. Learn more about Sign in with Apple. 

On your iPhone, iPad, iPod touch, or Apple Watch

1. Open the Settings app, then tap your name.

What happens if you stop using Sign in with Apple with an app

When you stop using your Apple ID with an app, you're signed out of the app on your device. The next time you visit the app or its associated website, you can either select Sign in with Apple to sign in again, or create a new account.

If you choose to use Sign in with Apple again, you're signed in to the same account that you previously used. Some apps might let you create a new password for your existing account so you can sign in again without using your Apple ID.

If you delete your account in an app where you use Sign in with Apple, you might receive an email from Apple that the app has revoked your Sign in with Apple account. If you want to create a new account with that app, you have to share your name and email address with the app again or create a new account using Sign in with Apple.

Cheers.

Glacier70,

Thank you for checking. If it isn't in the list of apps using your Apple ID, that would seem to indicate that it isn't using your Apple ID. What are you seeing that leads you to believe that it is using your Apple ID?

Regards.
