Hello. We have different login scenario.

1. Using basic login with username and password
2. Using mobile phone number to login
3. Using X509 certificate to login

Previously we use Gluu open source OpenID project. With this project we are using acr as query param and so the Gluu show different login page for each acr. How can I achieve this in Keylcoak. Does keycloak support acr or not?
