This is one of the core use cases for why FIDO Cross-Device Authentication was created. To be able to use a passkey to sign in on a shared device, a device you don't control, or a device where you just need temporary access to something.
On the one hand, that seems really important and I'm happy to know it exists.
On the other hand, I thought I had fully researched how passkeys work and literally never came across it.
So it kind of just continues to support my concern that passkeys are just too complicated to understand. If I'm at another device I need to log into, I would have just assumed I couldn't.
There needs to be a simple mental model for users. I'm not saying passkeys can't underlie that, but I think the UX still just hasn't been fully figured out yet.
