[keycloak-user] How to integrate 3rd-party 2FA with Keycloak

Hello all, is there any way to integrate a 3rd-party 2FA with Keycloak so that the OTP code is validated by the 2FA outside Keycloak? My team is using Authy for 2FA and I'm trying to figure out how to integrate it with Keycloak. Thank you, Hyunji
