Is this suited for github?

  • Yes, this is suited for github

To Reproduce

  1. Signup a user
  2. Link a social provider
  3. try to remove the social provider with authClient.unlinkAccount()

Current vs. Expected behavior

Provider should be unlinked, but the route returns an error:
POST /api/auth/unlink-account 400

{
    "code": "YOU_CANT_UNLINK_YOUR_LAST_ACCOUNT",
    "message": "You can't unlink your last account"
}

This happens even when multiple providers are added. The invalid change was introduced in #1803. The unlinkAccount function now checks if a account with the same provider exists and throws if not. This completly breaks account unlinking.
