I’m raising the issue on the current text, I already provided text if the original append.

Process-wise it does. This is a brand new concept *here* and was not mentioned in the charter or any use cases. Therefore, out of scope. 2. The current text provides all the information needed to imement. No one raised an implementation issue on the current text. 3. Refresh token do not provide anonymity. An implementation could but this was never considered in the design. 4. If you have suggested text, present it before the WGLC is over. I am not adding issues to my list without suggested text and wg consensus.

There are many use cases for refresh tokens. They are basically a protocol feature used to make scalability and security more flexible. Anonymity was never part of their design, and by the nature of this protocol, is more in the domain of the resource server (based on what information it exposes via its API). In fact, your email if the first such suggestion of anonymity.

A resource does not need to query the authorization server to see if the access token is valid.This simplifies access token validation and makes it easier to scale and support multiple authorization servers. There is a window of time when an access token is valid, but authorization is revoked.

The scenario is that a client asks the user for access. The user wants to grant the access but not tell the client the user's identity. By issuing the refresh token as an 'identifier' for the user (as well as other context data like the resource) it's possible now to let the client get access without revealing anything about the user. Recommend that the above explanation be included so developers understand why the refresh tokens are there. _______________________________________________ OAuth mailing list OAuth@ietf.org<mailto:OAuth@ietf.org> https://www.ietf.org/mailman/listinfo/oauth
