For a while I thought #PassKeys were like a tech hype thing so big tech could lock us into their ecosystems even more, and then I started looking into them and their advantage became far clearer to me. They still have a bunch of problems for people like me that change their devices frequently, at least in internet time.
I dislike the idea of being locked out of my stuff because my device is bricked, so I started looking for ways to use PassKeys with something like #KeePass databases. The bad news for us blind folk, the more accessible Keepass app doesn't have PassKey support. The far less screen reader friendly #KeePassXC has far better PassKey support, but, as I said before, not half as screen reader friendly as the OG KeePass is, unless I am missing something.
#StrongBox, which is accessible on iOS can work with PassKeys though. This way, you can't be tied to one device.
