> Phone-based WebAuthn systems are immune to that Do they assume the OS is locked down and secure? I mean, clearly if someone has a remote desktop view for my machine, then they can act as me, including any check for available hardware. The same should apply for a phone, yes? If so, that sounds like my bank will never formally support running on a PinePhone or other user-inspectable/modifiable system - they will simply say they require a full chain of trust for the OS. I'm glad the (relatively) open arenas of macOS and Windows existing, and that people have 10+-year-old machines, forcing my bank to support alternate login methods for less-trustworthy systems.
