I had my first experience of computing with the KDF9 at Birmingham
University in 1970.

The University had an early online system called COTAN; a network of
teletypes connected to the KDF9 via a PDP8 front-end processor. In
theory only post-grad students were allowed to use the system, however I
(and quite a few others!) discovered that the passwords were stored on
the disk in clear text and were accessible from a punch-card job
submitted through the same account. We like to think that security has
improved a lot since then but sometimes I wonder...
