The Windows version used to be shit. That’s no longer a problem. That’s about the only negative I remember. Otherwise you can have it doing a lot of work between devices or only sending when you feel like it. I force stop it on my phone and then invoke through share when needed.
I brought up Syncthing as it will function the same way, in a more hands off way (by choice if you want, automagically or forced) if you needed to share files/folders between devices. Not only for passwords.
