Enabling Web Part personalization without user registration

[Anonieko]

Scenario:

Web Parts features (like design mode) require the user to be
authenticated and registered.

But what if you don't want the users to go through registration but
still enable personalization ?

Answers:

Alternative 1:
Use Windows Authentication (good for intranet)
Modify Web.config to have

<system.web>
...
<authenticati on mode="Windows"/
...
</system.web>

In IIS virtual directory, right click properties--> disable
"Anonymous" access and enable Windows Authentication


Alternative 2:
Use anonymous personalization trick:

"The specified display mode is currently disabled on this page. Make
sure personalization is enabled for the current user."
