I don't understand. Is the joke that the person's PIN is actually just "2" because they hit "x" and it cleared everything that came before it?

[–] [email protected] 7 points 1 day ago (1 children)

The joke is someone remembers PIN by pattern/muscle memory and is baffled when the keypad is randomised and numbers aren't where they should be.

[–] [email protected] 1 points 1 day ago (1 children)

Ahhh, wow. I really missed that one. Thanks for the explanation.

I don't think I've ever encountered an ATM that's scrambled the keypad before. That would truly trip me up

[–] [email protected] 2 points 1 day ago

Of course it won't be like that on physical keypads.

But...

That's the hardest 12345 I've inserted in my entire life

6 and 9 are in the right place, you are fine.

[–] [email protected] 10 points 2 days ago (1 children)

Are you hitting on me? 🥺👉👈

[–] [email protected] 2 points 1 day ago

Only with your consent.

Because otherwise the cops get called when I get that good hit in.

[–] [email protected] 2 points 2 days ago

Never fear, citizen! It wasn't really ever your money, anyhow! 😁

I installed an NFC door reader at work. You can add a backup pin. But the reader is tall and it's only two rows so you get

9 3

8 7

2 6

5 1

4 0

it's HIGHLY infuriating to find the numbers for some reason

[–] [email protected] 3 points 1 day ago (1 children)

I pretended I was entering my PIN on it, got annoyed, and gave up.

[–] [email protected] 2 points 1 day ago

Yeah, I don't know what it is, It's random every time but there's just something so unnatural about the two column... Maybe we're just so trained for 3x4 pads...

[–] [email protected] 9 points 2 days ago (1 children)

So you're saying this whole thing is your fault.

[–] [email protected] 2 points 2 days ago

Yes, it absolutely was; But I blame the door company that I was with for a decade, that ghosted me for a month until it was too late for me to get anyone else to install before we re-opened.

They came out, quoted, said it was a 1 day easy job reducing 2 floors to 1. Just moving the controller and they had nothing on the books. Then poof. Called them tech, the dispatch, left messages with the Secretary.

Unifi door controllers are kinda of annoying, but they work, they're simple to install, and they cost me $0 per month instead of $250.

Runescape has trained me for this

[–] [email protected] 6 points 2 days ago

I never seen atm does this as they all have physical keypad, only those card machine. We have to tell customer that it's randomised and explain the security advantage to them, which they will understand.

[–] [email protected] 16 points 2 days ago (1 children)

How irresponsible. I almost forgot mine seeing this.

[–] [email protected] 2 points 1 day ago

I accidentally learned someone's PIN number here, and immediately forgot my mother's name.

[–] [email protected] 8 points 2 days ago* (last edited 2 days ago) (2 children)

Why mix up all the numbers, but not numbers 9, 5 and 6?

[–] [email protected] 29 points 2 days ago (1 children)

If the randomizer algorithm isn't allowed to leave any numbers in their original position, it sacrifices a tiny bit of security and a tiny bit of processing power, and a tiny bit of disk space, for no real benefit.

[–] [email protected] 5 points 2 days ago

Yeah it's like how the optimal cypher was like 11 swaps

More like 6969 and the 5 is a red herring

Red herring's watch from the corner?

I'll just put this with all the other fire.

[–] [email protected] 91 points 2 days ago* (last edited 2 days ago) (3 children)

I have a workaround for that! Take out your phone and search for a hidden app called "phone" (should be pre-installed). There should be a "keypad" tab. There you can type in the pin from muscle memory to get the actual numbers.

[–] [email protected] 5 points 2 days ago

I one time opened netflix to do this

[–] [email protected] 2 points 2 days ago (1 children)

You're out of luck if you need the letters though, because phones and PIN keypads don't have the same letters on the same numbers.

[–] [email protected] 7 points 2 days ago (2 children)

I remeber letter on keypads when I was like 14 and using sms on a keypad to text my girlfriend on a Nokia phone. Why are you still using that?

[–] [email protected] 5 points 2 days ago

I used to be able to type out a full text with my phone barely opened in my pocket in class, certainly can't do that with touchscreens 😅

These days I can type pretty fast on a touchscreen but I do sometimes miss the old days of unique flip phones compared to the boring slabs of glass we get now.

Helps remembering pins

[–] [email protected] 41 points 2 days ago (2 children)

except phone keypads and computer keypads are inverted.

[–] [email protected] 3 points 2 days ago

Maybe the calculator would be similar?

[–] [email protected] 56 points 2 days ago* (last edited 2 days ago) (1 children)

except phone keypads and computer keypads are inverted.

True.

But this isn't about computer keybads, but ATM keypads and they are the same as my phone keypad.

[–] [email protected] 9 points 2 days ago

You are correct. I was assuming they'd be more like 10-keys. Google images shows they're usually in the phone orientation.

[–] [email protected] 11 points 2 days ago

@TheBat

Brilliant! I wish my #bank 's #ATM was like this!

Right now, I have to cover my PIN-entering hand with my other hand, and then do a whole bunch of fake button presses, in order to hopefully confuse any hidden cameras. Hopefully. Maybe. It's absolutely maddening, and it probably isn't actually secure because real button presses require more force than fake ones.

If only the keypad was randomized like this, entering my #PIN securely would be easy. 😭
