It's neither your actual fingerprint nor a random key - it's more complex. When you create a passkey, your device generates a random private key and stores it in the secure element. Your biometric (fingerprint/face) is just the unlock mechanism for that key, not the key itself.

⚠ So if you delete and re-register a new passkey, you will not be able to restore your old private key!
