Re: [webauthn] Clarify how a user can authenticate from multiple devices (#151)

@knightcode Correct, but remember that techniques like browser fingerprinting can likely narrow the searchable space down to a manageable size. Then the website could use the silent probe to exactly identify the user without the user's consent. This does presuppose that the user has at some point authorized a credential creation for that site, but it's far easier to confuse a user into doing that once than into doing it every time you want to identify them.
