I used lophtcrack to get the windows admin password to the computer lab PCs in high school :)

Yep, and the password was 'driver'.

In my school's case it was 'passwd'. No cracking needed to obtain that one though, the admin had it written on a post-it on his monitor.

My school's domain admin password was 'school' (later changed to the school's name with O->0 substitution). It's marginally better than their VNC password though, which was 'vnc' (VNC Server was installed on every machine in the school).

Actually it was bhs-2020 still remember it after all these years

At my school the password was the person’s username. Someone guessed it one day. Which in hindsight was inevitable when the login screen was exposed to hundreds of bored kids every day.
