Auto logout? Request re-authentication from the server?

2008-07-02 Thread Simon Josefsson
Hi. Is there a best practice on how Openid consumers can find out whether re-authenticating the user, via the OpenID server, once in a while can lead to improved security? The security of normal one-time password systems (SecurID, SMS codes, Yubikeys, ..) can be improved if you ask for a new

One parameter of PAPE was allowing the RP to specify how long it had been since the OP had authenticated the user. There is a PAPE working group right now, if you were interested in looking at how your suggestions would be incorporated, I am sure they would welcome you to the group. I've

So far, neither OpenID nor CardSpace define the notion of a session, so no common logout is possible within the standard protocols. What we do in our code at NetMesh is to add a convention where RP-URL?lid=OPENID is the same thing as submitted OpenID URL in the first form, to which

well with OpenID atleast, I think we can easily design a logout extension, where an RP can register it's logout handler with OP during login flow (checkid_immediate/checkid_setup) and the OP could call each of the RP's logout handlers (in the browser) that are registered with the current
