Should I use passkeys or Sign in With Apple

I’m a little confused with the introduction of Passkeys. I was playing on using Sign in With Apple for my account creation and login. My understanding for passkeys is that they are deployed after the account is used as a replacement for the password.

Can I create an account from passkeys or is it only bolted onto an account after it is already created through a different schema?

Sign in with Apple and passkeys are different offerings, so which you want to use depends on your use case. With Sign in with Apple, you're getting an entire federated account that is tied to a specific Apple ID, which (depending on your use of the API) may have its own concept of fields like the user's name or email address.

A passkey, however, is just a credential; like a much much more secure password. Passkeys aren't federated through a separate service, don't have any notion of account information (it's up to you to handle this), and can be shared among people who want to have access to the same account.

Which you use depends on what you're looking for for your accounts. You can create accounts that exclusively use one or the other, or support both, either way without any need for handling passwords.
