Re: [webauthn] How to know if a user has already registered a device? (#1749)

Well, even an `exists()` checking existence of a public key credential:

- locally (on the platform)
- for the current origin
- blocked in iframes
 
would be really simple, without tracking info, and be helpful in 90% of the use cases to guide users.

I'm also surprised webauthn is supposed to work in iframes. IFrames are notoriously "unsafe by default" since you can eavesdrop and even manipulate anything that happens within. But that's another topic.
