If you want to check for authenticated users in your template then      if user is authenticated         lt p gt Authenticated user lt  p gt     else         lt  -- Do something which you want to do with unauthenticated user -- gt     endif

Update for Django 1 10   is authenticated is now an attribute in Django 1 10  The method was removed in Django 2 0  For Django 1 9 and older  is authenticated is a function  You should call it like if request user is authenticated          do something if the user is authenticated  As Peter Rowell pointed out  what may be tripping you up is that in the default Django template language  you don t tack on parenthesis to call functions  So you may have seen something like this in template code     if user is authenticated     However  in Python code  it is indeed a method in the User class

Django 1 10   Use an attribute  not a method   if request user is authenticated     lt -  no parentheses any more        do something if the user is authenticated   The use of the method of the same name is deprecated in Django 2 0  and is no longer mentioned in the Django documentation    Note that for Django 1 10 and 1 11  the value of the property is a CallableBool and not a boolean  which can cause some strange bugs    For example  I had a view that returned JSON  return HttpResponse json dumps        is authenticated   request user is authenticated       content type  application json      that after updated to the property request user is authenticated was throwing the exception TypeError  Object of type  CallableBool  is not JSON serializable   The solution was to use JsonResponse  which could handle the CallableBool object properly when serializing   return JsonResponse        is authenticated   request user is authenticated
