Extensibility in authentication schemes is a bad thing, given how they are deployed and the difficulty of changing them. No existing authentication scheme is extensible (explicitly). EHL > -Original Message- > From: oauth-boun...@ietf.org [mailto:oauth-boun...@ietf.org] On Behalf > Of M

Shane, We have been working on openID Connect (formerly known as openID AB) for some time. If there are standard ways to do things in OAuth 2.0 that we can reuse then it saves us from inventing custom extensions for openID Connect. We have identified the need to request multiple tokens as one

I think it's vital to have the GET and POST parameters make sense to every developer. I worry less about the authorization header since a developer implementing it will honestly be a stronger engineer. Here's what I said earlier in the thread about my motivation: > Did a full read through of draft

I definitely don't want to change the Authorization header naming scheme. I believe it should stay 'Bearer' because that's what the token is. We could make it... Authorization: Bearer access_token=vF9dft4qmT If that helps with consistency. I don't think we should be associating the term 'acce

What does this mean for the HTTP Authorization header naming scheme for bearer tokens? As I understand this decision, we are discussing whether to standardize on the name "access_token" when a bearer token is sent as either a URL query parameter, or in a form POSTed body? Currently the HTTP A
