iPad usability is in a really weird place. It's definitely the least "usable" of Apple's platforms, and to be honest I probably wouldn't be an Apple user at all if all they had was iPadOS and iOS. macOS is still attractive to me (the Liquid Glass theme notwithstanding). For the record, I split my password manager use between Apple Passwords and [now] self-hosted Vaultwarden. Each has advantages, and while I'd like to just use one, having two is working okay for me for now.
