[keycloak-user] Iframe login form

Hello, We are currently evaluating keycloak as a solution for idp/sso, and are currently looking at how integration should look like. In order to keep the login experience seamless, we have an iframe approach working, and have locked down the X-Frame-Option and the Content-Security-Policy for frame-ancestors to limit it to our site/domain. The redirect is captured by the iframe and the code is passed to the main page and the keycloak.js is initialized with this to get the token. Is this supported and if not why not? I want to make sure that there isn't something I am missing in how this works from a security and usage point of view. Thank you, Greg
