I say “in theory” because after you log in again, you’re prompted to download the iCloud Passwords extension for Chrome. According to Apple’s support page, you’ll need to have two-factor turned on for your account to have access to the feature, which is probably a good choice since, in theory, you’re going to be syncing all of your passwords. Checking the box will cause a login prompt to come up, along with a request for two-factor authentication. The latest version of iCloud for Windows 10 includes “Support for iCloud Passwords Chrome Extension” in the list of new features, and when you open the app, there’s a new Passwords-syncing option. It’s already in the iCloud for Windows 10 app, but there’s just one small problem: the Chrome Extension isn’t available yet.
Users caught between Apple and Microsoft may now have an easier time managing passwords: it looks like iCloud Keychain is coming to Windows 10 as a Chrome extension ( via MacRumors).
