Proposal: An anti-phishing compromise

2007-02-01 Thread Josh Hoyt
Hello, I've written up a proposal for an addition to the OpenID Authentication 2.0 specification that addresses the phishing problem. I've had some off-list discussion of it, and I think it may strike the right balance. Please provide feedback. Josh Background == We have had a lot of

I think we all agree that talking about the method used is far more useful, though with this proposal we're really trying to balance it with simplicity in the authentication protocol itself. Maybe it is better to phrase the discussion around if the user provided a secret (password) to the OP or

OA2.0d11: Minor nit-pick regarding normalization

2007-02-01 Thread Martin Atkins
Hi, This is a really minor thing I just spotted due to leaving my browser open on the relevant part of the spec and coming back to it later. :) The normalization table in appendix A.1 lists several examples of the normalization of URIs. The last few examples are as follows:
