When allowCredentials is enabled a list of identifying information for registered credentials is sent to the Authenticator upon authentication. The Authenticator uses this list of credentials to identify the credential to use for authenticating the user.

Possible values:

• enabled: Sends a list of credential identifying information to the Authenticator, allowing the Authenticator to identify the proper credential to use for authentication.
• disabled: Don’t send a list of credential identifying information to the Authenticator and therefor allowing the Authenticator to rapidly identify the proper credential to use for authentication.
