iCloud for Windows has made it possible for users to access their photos, drive, mail, contacts, calendars, and bookmarks between devices for some time. With this new 12.5 update, you’re now also able to directly manage the passwords in your iCloud Keychain. Granted, syncing and managing passwords across multiple devices isn’t a new concept, but this does make macOS/iOS-to-PC transitioning easier.
Once you've downloaded the update you'll have the option to look up, edit, copy, paste, add, or delete the passwords you have stored. You also can set up and manage additional Keychain accounts for individual users.
