If my phone explodes like a Samsung surprise, and my laptop turns into a spicy pillow;
I can in the worst case scenario, still log in via the local library PC.
I could borrow a device from a friend, or buy a second hand Thinkpad and use that.
That is to my knowledge, not possible with a passkey device.
If you’re remembering all your passwords there’s a good chance they’re terrible, you frequently re-use them or both. That really helps attackers e.g. when they use leaked passwords to run credential stuffing attacks on your employer.
You just wrote two comments bashing a technology you admit you didn’t properly educate yourself about.
For android, the passkey is clone-able iirc, but again, it's an expensive smart device.
So now I am expected to have at a minimum, two use-able smart phones, per family member. Iphone? Frankly, fuck that shit. Too expensive.
Android, I can manage it. But doing that for all family members is not financially viable.
Also I do use a password manager and an encrypted text file. (Not smart, I know. The file is basically a backup)
But I really cannot expect people like my mother to understand how to set up a passkey. Much less, how to setup multiple for the off chance one is lost. Add onto the fact that Yubikey does not support twins, and many services do not support multiple passkeys.
In terms of computer literacy, using my mother as a baseline (Age:Mid50s) the current passkey system is non-viable.
So just make multiple passkeys on the different platforms/devices.

No, you can have passkeys on laptops and desktops. It doesn't need to be a phone. Hardware tokens can be had for like $20.
