[Zope] zope users / passwd

[Michel Vayssade]

Hi,

is there a way to force zope to ask the user for a new user_id/passwd,
overiding the old one previously entered ?

so the user can do some work as userone
then going in another part of the site
entering usertwo/passwd and doing work as usertwo
etc ...

is there some how-to about that ?
thanks
