> Passkey synchronization provides convenience and redundancy in case of loss of a single device. However, it's also important that passkeys be recoverable even in the event that all associated devices are lost. Passkeys can be recovered through iCloud keychain escrow, which is also protected against brute-force attacks, even by Apple. > iCloud Keychain escrows a user's keychain data with Apple without allowing Apple to read the passwords and other data it contains. The user's keychain is encrypted using a strong passcode, and the escrow service provides a copy of the keychain only if a strict set of conditions is met. > To recover a keychain, a user must authenticate with their iCloud account and password and respond to an SMS sent to their registered phone number. After they authenticate and respond, the user must enter their device passcode. iOS, iPadOS, and macOS allow only 10 attempts to authenticate. After several failed attempts, the record is locked and the user must call Apple Support to be granted more attempts. After the tenth failed attempt, the escrow record is destroyed. > Optionally, a user can set up an account recovery contact to make sure that they always have access to their account, even if they forget their Apple ID password or device passcode. https://support.apple.com/en-us/HT213305 https://support.apple.com/en-us/HT213305 This just looks like passwords with extra steps and making it harder for customers to leave Apple's ecosystem.
