I wish they would add Linux support. I use Linux and macOS almost 99% of the time and don't use Windows. Please Apple, make it happen.
And OpenBSD support too, while at it. (Maybe just release the source code for the native blob.)
I wonder if that's due to a technical limitation (maybe it uses an OS-native hardware secret storage mechanism that Linux does not offer), or just because Apple refuses to acknowledge the existence of Linux on the desktop.
So for now, I stick with my pass setup.
