+Speeding up the tests
+---------------------
+
+In recent versions of Django, the default password hasher is rather slow by
+design. If during your tests you are authenticating many users, you may want
+to use a custom settings file and set the :setting:`PASSWORD_HASHERS` setting
+to a faster hashing algorithm::
+
+    PASSWORD_HASHERS = (
+        'django.contrib.auth.hashers.MD5PasswordHasher',
+    )
