Hi Bruno, thanks for your insights. The recommendation is not only based on security considerations but just utility. As soon as one wants to integrate federated login or multi factor authentication, ROPG reaches its limits. Moreover, how do those teams implement user registration and user ac

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

I would also seriously look at the original motivation behind ROPC: I know it has been deployed and is used in quite a lot of places but I have never actually come across a use case where it is used for migration purposes and the migration is actually executed (I know that is statistically not a ve

Agreed. Plus, the Security BCP is already effectively acting as a grace period since it currently says the password grant MUST NOT be used, so in the OAuth 2.0 world that's already a pretty strong signal. Aaron On Tue, Feb 18, 2020 at 4:16 PM Justin Richer wrote: > There is no need for a grac

The security topics says MUST. If you want to change that, then that is a different discussion. :) In the OAuth 2.1 document, it would just not be included. Applications can continue to be OAuth 2.0 compliant. BUT ... if there are valid, new use cases. Please describe them! Perhaps it should not
