I think "Sign in with Apple" is unique that Apple allows the users to hide their email address https://support.apple.com/en-us/HT210425 https://support.apple.com/en-us/HT210425 which makes it extremely hard to migrate away, unlike other federated login system where you can at least get users' email addresses, allowing you to create a proper email+password login later on.
- the_arun 6y agoI think it is very private. The third party app cannot sell the attached email address to others. But I agree if you sign up with the third party using your apple id, they will not know you which may end up in creating second account. If they don't have account linking feature, it will be messy.

- gowld 6y agoHow is that? It's the developer's choice of they want to let me add a second login to the same account.
