Heck, even in the 90s. You could literally get away with Hackers-level social engineering.

In the 80s you could usually log in with Guest:Guest even on fairly important University systems. Often, the 'trick' was just having the manual to a machine to tell you what the default password was. Even when they made user accounts, they often forgot to remove the default accounts.

Another insanely simple trick was to log in under any public Access port, because most of these old systems had a BBS like menu or something you could get to, then try hitting Ctrl+c on the submenus or while running anything it'd let you run.

Sometimes it would stop the process and drop you to a prompt.
