Will the sub(user identity) be maintained when I reconnect Sign in with Apple?

I want to know if the user identity(sub) maintains the same when the user un-links the linked app from the Apple ID setting and re-links it.

I would be grateful if you could give me an reply.

Hi JAEHOON_LEE,

Yes, the user identifier and private email address remain unchanged for the same developer account and all apps authenticated with Sign in with Apple. However, even though the same user may decide to change their full name or use a different, real email address on a subsequent account creation, the user identifier will stay the same. This is way it should be used as the unique identifier for your users.

Cheers,

Paris
