Hi Guys, I really understand the security and motivations behind ROPC and I'm not against the decision it is deprecated. Actually I see many devs and teams using ROPC to deliver a better UI experience in Mobile apps and easy integration. They try to follow specs of RFC 8252 and AppAuth isn't easy to use. Many bugs shows up in the way, and it's not a good user experience at all. At the end of the day, they became to use ROPC as an alternative. Tremendous easy to implement compared against AppAuth.
My question is, we are really prepared to go away from ROPC? In one hand the best practice says: Use AppAuth for Native apps. But in this case the time and efforts the teams need to implement it in a good manner is substantially high if we compare against a SPA Frontend using javascript oidc. So my point is, isn't better for us before remove oidc, try something to improve a better and easy integration with native apps? /Bruno On Tue, Feb 18, 2020 at 6:57 PM <[email protected]> wrote: > Send OAuth mailing list submissions to > [email protected] > > To subscribe or unsubscribe via the World Wide Web, visit > https://www.ietf.org/mailman/listinfo/oauth > or, via email, send a message with subject or body 'help' to > [email protected] > > You can reach the person managing the list at > [email protected] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of OAuth digest..." > Today's Topics: > > 1.
