> Being limited to only devices from a single vendor is horrible, and a firm no from a lot of people.

Maybe for a lot of tech people, I don't think the general public understands the risks enough to care.

I literally presented you with the solution in the sentence before. Buy a usb c dongle key. You pay 20 euros to NEVER have to remember a single password ever again. Seems like an ok trade off to me. Likewise you can register multiple passkeys for multiple devices, so long as you do it in sequence (first Apple, then Android) etc. Really it takes very little getting used to. Ever tried to fill out a crap password form which wants 7 special characters but no dashes but uppercase but not uppercase Y and so forth.
