Low risk of lockout, but about as high-severity as one can imagine. Yes in theory sites should offer a password fallback, but how many actually do? And of those that attempt it, how many get it right?

Not even Google reliably lets you fall back to a password, according to the comments in this article. Losing access to your google is anywhere from major inconvenience to professional disaster.

Expecting every user (site using passkeys) to implement complicated flows is a time-tested recipe for disaster, and it's a bummer to see that unfolding yet again with passkeys.

I logged in with my google password (on my TV, the other method using my phone wasn't working for some reason) the other day even though I normally use a passkey from my phone or computer. It worked just fine.

Sometimes it works, sometimes it doesn't. I've had Google block my login because it was sus (it was a new computer or something...) and they wanted to verify a whole bunch of information. If you haven't given them that info, you just get locked out.
