Hmm

Used to work at a pretty secure place. Each button had a small screen on it, and the numbers were randomized. So apparently this is an actual concern.

Scramble pads. We have them where I work. Damn password can change a few times a week without warning. Gone for lunch? Well good luck getting back in until reception comes back to tell you the new code.
- Had this once at a retail store while paying. Entering PIN without muscle memory. .... Weird and almost made 3 errors which would have blocked my card.
- Neat, animated gif here

Those also prevent observers from being able to learn the code by watching someone type it in from a distance.
- That's smart, but probably frustrating as an authorized user.
iirc this is a GrapheneOS feature too
I've seen this on payment terminals too. It's real annoying when you're used to do the same motion all the time. But safer obviously.
I wonder if this is a problem for dyslexia?

You can even tell that the 1 is touched more often on the top, meaning it is 'the top' one. Then 9 on the top as well, meaning you probably came from the top when moving 1 to 9. Then 7 is damaged on the left, probably because you come from the 9 on the right. Then apparently everyone just punches the shit out of 0 I dunno.

I bet everyone remember the first two digits correctly but once in a while makes mistakes in the last two digits. So first two digits gets pressed more often. Although I don't see any discoloration in other buttons, so maybe not.

All these comments and speculation on what the code might be. But it's irrelevant.

The light is green, the door is already open

Bonus: Address of the building is 1790.

That was how the code to my grandpa's ward worked. If you could remember the street address, you knew the code to get out of the Alzheimer's wing.
Or year of construction or company start was 1970.

That’s definitely the worst keypad wear I’ve ever seen :D

They actually make versions these days where a display randomises the numbers, so that it doesn’t form a discernible wear pattern.

Of course, you do have to wonder if this is actually a thing to be worried about, or rather something we all ‘know’ from spy movies. Usually the easiest way to bypass these is to just walk in after someone…

Guy in highlighter vest:"Hey buddy can you hold the door?"
90% success rate
- It’s silly but it’s true. Especially if you’ve got a package, a ladder, etc. Nobody’s going to hassle a dude carrying a ladder because he’s clearly Doing Something Important.
  When it’s a regular old apartment building you don’t even need that. You can just wait until someone walks in and just follow them through. Happens all the time. Which is why I make sure to always pull security doors closed behind me. I’d rather not be the cause of a break-in or worse.
- I used to geocache a LOT years ago, don't do as much now. But it was crazy how much people would ignore whatever weird thing you were doing if you had a high-vis vest, clipboard, and hardhat. I used to joke you could damn-near walk in anywhere and nobody would blink.
- Why hitman is the most plausible stealth game, even though it has it's own shenanigans too.
- I once worked in a SCIF and (with one exception in the morning where a security officer could just check your ID card to speed it along) even if there was a large group of people entering every single one needed to close the security door behind them and let the next person use their key. If someone, especially someone you don't recognize, asked you to hold the door you were supposed to say "no" and inform a security officer.

Plot twist: it explodes after 3 wrong guesses.

It looks like it already has a couple of times already.

Happy 54th birthday soon

Is it 010119700000 or 197001010000?

Most likely 1970
- Start of the Unix epoche, everybody could have social engineered that. 😁

hmmm, I think I might "wear" out some numbers on my pad. Not the ones used but if I make it look this obvious I should drastically increase the resistance to general attack as no one could pass this attack up.

The newer keypads make you touch two random numbers before you can enter the code, to prevent this very problem.
- I aint paying for fancy keypads.

The 90s.....

The SEVENTEEN 90s, that is...

Hint: the beginning of time

I once knew a guy that was really stupid. He got angry very quickly and had no patience for anything.

He had a lock on the button for his garage door opener that was a slider switch, he caved it in because he pressed it really hard instead of just looking and seeing that it's a slider switch

That's still 256 possible combinations. Isn't it?

Assuming 4 digit password it's 4 factorial, 24 combinations
unless the length is fixed, e.g. 4 chars (in which case there can't be repeating characters)

Obviously this isn't on Liberty Island or 0 1 4 and 5 would be all worn down.

So there's 24 options left.
