In the 1970's Stanford had IBM 2741 hardcopy terminals spread around campus networked to an IBM 360/67. Account passwords were three characters. During logon, the password prompt would overprint a three-position blob of about nine random uppercase characters, so the subsequently-typed password would supposedly be masked by the blob. However, everyone typed their passwords in lowercase, which were trivial to discern against the uppercase background blob. That meant you could usually walk up to any terminal, peruse the hardcopy typically left behind by the previous user, and easily logon with their account and password.

Right at the start of the .com era, I was working for a large retailer overseas. We watched with great interest as our competitors launched an online store months before us.

With good timing, you could change the delivery address but leave the payment method alone... all that after having filled the cart with your favorite items.
