!!! Overview
[{$pagename}] is when a [website] ([WebAuthn Relying Party]) needs to obtain proof that it is interacting with the correct user.* The [WebAuthn Relying Party] generates a challenge and supplies the [browser] with a list of [credentials] that are [bound|Binding] to the [UserId]. (this [binding] was performed in [WebAuthn Registration]) 
** The [WebAuthn Relying Party] can also indicate where to look for the [credential], e.g., on a local [built-in authenticator|Platform Authenticator], or on an [external authenticator|Roaming Authenticator] over [USB], [BLE], etc.
* The [browser] ([WebAuthn Client]) asks the [authenticator] to [[Digitally Signed]] the challenge.
** If the [authenticator] contains one of the given [credentials], the [authenticator] returns a [Digitally Signed] [assertion] to the [Website] after receiving user [consent].
* The [Website] forwards the [Digitally Signed] [assertion] to the server for the [WebAuthn Relying Party] to verify.
Once verified by the [WebAuthn Relying Party], the [authentication] flow is considered successful.
