[keycloak-user] SSL connection to Keycloak Server

Hi guys, I have 5 web apps that use Keycloak for authentication. But none of them are using SSL yet. How is the practice done? Do i need to set SSL on the Keycloak server for the Keycloak authentication page to have the secured lock symbol? Or is setting SSL to my web apps enough? I am not very clear about Keycloak and its SSL implementation, I hope someone can help explain to me. Regards, Kunal
