To support FIDO-U2F or Web Authentication with FIDO-U2F device, an authentication token for indicating the user passed the first step of multi step(factor) authentication is required.
FirstOfMultiFactorAuthenticationToken
is meant to support the scenario. Also, by makingAuthenticationTrustResolverImpl
return false for the token, existing spring security application can introduce Multi Factor AuthenticationProvider like https://github.com/ynojima/spring-security-webauthn with minimum modification.(maybe
FirstOfMultiFactorAuthenticationToken
is not proper naming, but I couldn't find another name.)
