  1. That's an interesting approach, but I think people regularly want to log in to the same site as different accounts without switching users or profiles. (Mine and my wife's gmail comes to mind.)

    Perhaps if profiles weren't such a pain in the ass to manage, that'd be different.

    And "yes, you're always logged in" is a pain on any public computer.

    Still... OpenID avoids multiple auth sources, and that minimizes the certificate distribution problem.

  2. Turning on the selection of certificates isn't that difficult to manage in Firefox. And maybe we can make extensions for people who do share computers.

    We are considering other options as well. Such as allowing multiple profiles attached to a single certificate (ideal maybe for family computers).

    But what we really like about certificated OpenID is the control that the user can have by distributing subsidiary certificates to agents. This is our vision.
