How to make the TFS Project Portal public?

Is it possible to make the Team Project Portal of TFS public to everyone? Currently I get prompted for 开发者_运维知识库a user and password when I browse to the portal. For me this isn't a problem because I have a user, but I would like to use the link to a work item (a link like this: http://mytfsserver:8080/WorkItemTracking/WorkItem.aspx?artifactMoniker=xx) to send to a colleague who doesn't have a user.

Where can I change this if it is possible?

As far as I'm aware this isn't possible because the person viewing the portal needs to have a Client Access License.

You may be able to use the Web Access application to get around this.
