[Zope] How to logout users when using LoginManager?

I've searched the zope website for tips on how to truly logout users, but I can't find any information. I'm using LoginManager, with GenericUserFolder. I see mention of cookie auth methods, but I have no idea how to use this. So, I'm using basic auth (I assume). Can anyone share some tips on how to logout users from a web page, using cookies or otherwise, allowing them to relogin as another user without having to quit/start their browser? Thanks..
