Apple apparently has an iCloud app for Windows that syncs passwords and provides extensions for major browsers. I had no idea.

The Windows app for iCloud Passwords works fairly well, no real complaints about it to share. It can sometimes be a bit clunky and slow, though that's likely related to my environment rather than the app itself.

Would love it a ton more if it could offer an experience similar to BitWarden where you can view notes linked to logins or autofill credit card details with a single click from the browser extension. But overall it's really helpful.
