This could definitely come in handy.
According to the API (Application Programming Interface) tools available in the betas, iOS 12’s AirDrop system will apparently include a password sharing feature, allowing you to store unique and intricate passwords in a secure, accessible manner.
The passwords can be shared directly through the iOS Password Manager via AirDrop.
On an iOS 12 device, open the iOS Settings app and go to Website & App Passwords. Then, select a login, tap on the password field and an option to AirDrop the login will appear. The login can be AirDropped to any iOS 12 or macOS Mojave device. Users on both devices are required to authenticate via Touch ID or Face ID before the password can be sent or saved.
The operating system will automatically suggest strong, unique passwords and the new feature is expected to work in both third-party apps like 1Password, as well as Safari. All of your passwords will be stored in iCloud Keychain no matter where they are created and they are synced across all of your devices.
Third-party password applications such as 1Password or LastPass will be supported by a new Password Autofill Extension that will let these password management apps to supply autofill passwords in apps and Safari, making it easier to enter a password stored in an app like 1Password or LastPass.
The API also hints at a feature that allows you to ask Siri to retrieve your passwords. Once a command like “Siri, show me my passwords,” is spoken, Siri will open up your iCloud Keychain after you authenticate your identity with a fingerprint, a Face ID scan, or a passcode.
iOS 12 is currently available as a developer beta, with public betas expected later this month and a final release anticipated in early fall.
Stay tuned for additional details as they become available.
