Where I work we once had a Novell 3.11 server...
The main problem was that the console password never asked for verification, so was prone to typing errors! This was easily overcome by use of the supervisor password. This was a god send for us as too many people (in my opinion) had console access.
I would suggest, as everyone else has done, that you should remember your password. I appreciate that repetition is the mother of succes here, as you suggested. With this in mind I would suggest you log on as the supervisor every day, even if it is so you remember the password.
Another suggestion is to have another supervisor equivalent, just in case the supervisor account gets locked. We used to keep the password for the supervisor account in a sealed, signed, and dated envelope in our on site media safe. This served three purposes:
1) It could be used in emergencies, i.e. when supervisor equivalent account became locked.
2) It meant that the supervisor account was not in regular use.
3) It maintained business continuity, i.e. if we were all wiped out simultaneously there was a means for someone else to take over.
Maybe you just need a memory upgrade?
