Dear Keycloak community, I'm trying to get the following functionality in my browser authentication flow: 1. Like "OptionalOTP" I'd like to get, after user login authenticator, an Option2FA (second authentication Factor) that will ask for a second factor of authentication according to some predicates (client IP, time, user role, ...) 2. I need more than OTP as second factor. OTP is one good solution, but I need to provide to the end user a set of 2FA, like SMS, MatrixCard and so on.(can be configured). But I also need to leverage on existing authenticator, so, my wish is to reuse existing or new Authenticator. In that sense, I tried to create a skeleton implementation - and share it through github, I really need some input from the community, if it sounds correct or if you have any better idea to implement such a use case. see . https://github.com/stevefavez/keycloakext class : ConditionalMultiFactorAuthenticatorDelegate I look forward for your valuable feedback. (By the way, I know that this feature should be implemented in the next release, but I must implement it on 2.x, because we're using rh sso.) Thanks in advance for your help. Best regards Steve
