[keycloak-user] Login Confirmation every time

Hi, I have a requirement where multiple users use shared terminals. I would like to have a “Continue to ${client} as ${username}?” prompt page that occurs after every (unprompted) authentication. (I.e. if cookie auth was successful, but no login form) So this would always be present when processing of a login that can occur without interaction if a cookie is still valid. When prompted, and it appears to the user that it is an old login from previous person, then I will present the option to “Login as someone else" (What I describe is different to the consent screen that occurs once per client per user.) Doe this already exist? Otherwise, should I be thinking of a RequiredAction for this, or an Authentication flow? Pointers appreciated. Thanks Rob
