Re: [Txauth] alternative charter writeup

I think it should be I struggled on how to capture that. The key element here is that there’s one device doing the request and another doing the interaction. This pattern is also used in CIBA and some UMA style flows, so it’s not just about the nature of the client but also about the nature of the users involved. 

So for now that’s firmly in “and other” but I’m open to suggestion!

This protocol will allow an authorizing party to delegate access to client software through an authorization server. The use cases supported by this protocol will include widely deployed use cases currently supported by OAuth 2.0 and OpenID Connect.

The protocol will be initiated by the client interacting directly with the authorization server (in contrast with OAuth 2 which is initiated by the client redirecting the user’s browser). The client will involve the authorizing party as necessary through interaction mechanisms indicated by the protocol.

The use cases supported by this protocol will include widely deployed use cases currently supported by OAuth 2.0, and OpenID Connect. In contrast to OAuth 2.0 and OpenID Connect, where the protocol is initiated by redirecting the user's browser to an authorization server, this protocol will be initiated by the client directly interacting with the authorization server..
