+Even good passwords consisting of 8 characters, can be broken
+in around 50 days (obviously this time varies a lot and also
+gets shorter and shorter over time). Do you think it is good
+policy to require users to change their password every 3
+months (as King's did until recently)?\medskip
+
+Under which
+circumstance should users be required to change their
+password?
