Yes, indeed. The keychain is kind of a big selling point. I'm planning to try and move onto BitWarden to keep my password management cross-platform and open source but it's not as well-integrated. It would be way better if it could sync the iCloud credentials instead of manually having to jump through hoops to get them in.

The Apple lock-in with my passwords makes me feel uneasy and probably way less likely to consider using other platforms as often for daily tasks.
