There’s much more to iCloud Keychain than meets the eye. Apple’s password-management system suggests strong passwords, autofills them whenever you need to sign in later, and syncs across all your devices. But you also can use iCloud Keychain to keep two-factor authentication codes (instead of relying on Google Authenticator) and access your passwords on Windows.
There’s been a lot of discussion lately about how Apple should make a standalone Passwords app. That’s because a lot of the more advanced features in iCloud Keychain are pretty hard to find. You have to dig into Settings to locate them.
There’s a workaround: I have a Shortcut that will add a convenient Passwords icon to your iPhone’s Home Screen. Using iCloud Keychain becomes a lot easier.
