[keycloak-user] Fwd: Native Android/iOS Keycloak Login

Hi, i am a newbie in Keycloak, i read that keycloak is very customizable, i would like to know if i can code an Android/iOS application to login to keycloak. The problem is, that, the examples i found always use a browser to input the user credentials. Is there a way to use some Keycloak API, to code a web service that receives [username, password] and retrieve Keycloak user data information(i.e. Roles, etc)? !!Thanks for any help!!
