Thank you to those answering my question on implicit for JS clients. The responses so far seem to represent what the security world is saying about the implicit grant - keep away from it other than for a few OIDC use cases.
Does anyone think it would be valuable to author a brief RFC to give clear OAuth 2 recommendations for JavaScript client developers? I mean - the OAuth 2 body of work just needs a few more RFC's, right? :) Aloha, Jim On 2/17/17 6:03 AM, sebastian.ebl...@telekom.de wrote: > > Same for Deutsche Telekom.
