So I wonder about this. The thing I want is supposed to be impossible, and FIDO tries to put technical measures in place to make it impossible. But passkeys have been implemented by open source applications. So technically I don't see how they stop me.
There's another weird thing. [EDIT: removed outdated statement about Firefox support]; and the BitWarden site seems to imply Passkeys require Google Play Services. What? Problematic, as I am moving to Lineage or something soon.
