I lost my passwords when I transferred to a new iPhone 13. Does anyone know how to retrieve them?

Note: If you enter your iCloud Security Code incorrectly too many times, you can’t use that iCloud Keychain. You can contact Apple Support on the Apple Support website to verify your identity and try again. After several incorrect attempts, your keychain is removed from Apple’s servers, and you need to set it up again.

To learn more about iCloud Keychain, see the Apple Support article Set up iCloud Keychain.
