I will nerd out about authentication.

If the computer is actually capable of determining that the voices speaking are the actual dudes, there is no need for a particularly complex password at all. A simple one stored only in the minds of Kirk, Spock and Scott - so that they don't write it down - would be better than something on a notepad or something on a hard drive that could be discovered by a bad actor. (No not Sonequa Martin-Green in this case lolololololololol)

I always thought it was so simple because the captain never changed the default password

"Destruct sequence 1, code 1-1 A."
"Destruct sequence 2, code 1-1 A-2B."
"Destruct sequence 3, code 1 B-2B-3."

Sorry Star Trek 3, I always thought your writers were being lazy when they came up with such a simple destruct sequence but it was actually an easter egg back to Let That Be Your Last Battlefield. Shatner did it way better in the movie I think.

Been re-watching the original series and there are lots of tidbits I either never noticed or have long forgotten. Not just that I didn't remember just how many episodes had interesting thoughts or issues with AI which is fun to re-watch in today's context, its fun to remember "easter eggs" from the movies that reference TOS. I'll be posting the episode and what I noticed, for my own pleasure and recollection.
