I have a AngularJs single page web-app that makes RESTful API calls to get secured data from our server (Play Framework). I originally set it up to be a public client using the keycloak.js adapter but I’m wondering if there’s a more secure way. Instead of having the redirect response (with the authorization code) come back to the keycloak.js followed by the request to get the access token, wouldn’t it be more secure to have the javascript post the returned authorization code to our server or just set the redirect url to an endpoint on our server to make the backchannel request (with client secret and id) for the access token? Then we can redirect the user to the appropriate location with the access token in the response? I guess I’m trying to make my RESTful api a confidential client, any input or direction would help. thanks. _______________________________________________ keycloak-user mailing list keycloak-user(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-user

Thanks for the follow up. I understand how having my custom javascript post to our server doesn't buy us anything. I'm more curious what you think about pointing the redirect_url to an api on our server that would take in the Authorization Code and make the backchannel call for the access token with the Client credentials. Does that seem reasonable or does this seem like overkill? thanks On Tue, Feb 23, 2016 at 1:11 AM, Stian Thorgersen <sthorger(a)redhat.com&gt; wrote: > As long as you use HTTPS and make sure you set redirect uris correctly > it's secure.
