!!! Overview
[{$pagename}] requires use a [authentication] [protocol] ([authenticators] and [Verifier]) to prevent possible [phishing] [attacks]. 


There are a number of ways to do this, including various [encryption] [protocols] and [Digital Signature] technologies that bind the [authenticator] output to a specific protected [channel]. 


One example of a verifier [{$pagename}] [authentication] [protocol] is [Mutual Authentication] [Transport Layer Security] ([TLS]). In this [protocol], the client signs the [authenticator] output and earlier messages that are unique to the particular [TLS] connection being negotiated.


At [AAL3], [NIST.SP.800-63B] requires authenticators that use a [verifier] [{$pagename}] [authentication] [protocol].
