You can choose the storage for your userdata yourself, 
which may be practical for i.e.

- huge user base and/or you also like to store adresses etc. easily.
- adding/changing users through mechanism outside of zope
- verifying users through mechanism outside of zope 
  (ie. apache's various mod_auth_*) for tasks outside of zope 
  (try to stream a .rm-file only to built-in authenticated users)


cheers.
