I understand that the passkey is stored on iCloud Keychain. That means you need an Apple ID account. Can I use passkey without Apple ID account? I checked on the simulator and even though I don't need to log in to my Apple ID account, I can still use the passkey. Please help me. Thank you.
Using passkey without Apple ID account.
Credentials used in Simulator are useful for testing, but are not true passkeys. Using actual passkeys requires a backing passkey provider. In addition to iCloud Keychain, there are several third party passkey managers available.
