Register a passkey on a different device or get a hardware key or whatever. Or call Microsoft support and complain to them. This doesn’t feeling like an honest discussion anymore.
Have a broken phone camera? Cannot scan qr codes.
Lost the phone? Cannot log into vital modern day accounts like email.
Your house burned down, and the passkey device with it? Say goodbye to literally everything.
Homeless (temporary or otherwise) persons, random local government sweep just trashes everything you own. Bye bye to the passkey again.
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.
Something I know is the only authentication method that can't be physically destroyed. When your customers are the masses every failure mode that can happen will happen, usually at the most inconvenient time.
What sucks about passkeys in abstract is that you want at least two failure modes that are uncorrelated— you're unlikely to forget your password and have your house burn down at the same time. Passkeys consolidate everything into to physical possessions which can be and are destroyed all at once.
