Put yourself in the role of a consumer for a second.

As a consumer, I don't give a shit. I use my driver's license to apply to jobs, my passport to fly, and a password (with 2FA depending on how much I / my employer cares) for everything else. I prefer whatever I use for 2FA to not be device-bound, because that's obnoxious, error-prone and constraining.

As a consumer, I don't see any reason for my auth to be more complicated than that.
