1234!? That's the stupidest combination I've ever heard in my life! That's the kind of thing an idiot would have on his luggage!

I have a pin lock on a shared device, that friends use occassionally. Of the three friends I have given guest access to, all three asked for their pin to be 1234, to which I said no. One had the audacity to follow up with 123456

I moved to Switzerland, and, well, PIN codes for credit cards are 6 digits here by default. And now I'm asking myself why noone else does this. I don't see hordes of Swiss people complaining about being unable to remember a 6-digit PIN at least.

Is there any difference it materially changes security? Where would the extra two digits come into play?

61 pins are used by 1/3rd of all people. So statistically, if I steal 61 debit cards, assuming I have 3 tries, and assuming people choose their own pin, I should be able to get cash off one in expectation.

Honestly that sounds sufficiently secure for what it is.

I think the least common PIN codes are fascinating. I'm surprised by the number of 7s in these. They looks like numbers you would end up with if you asked someone to think of a random 4 digit number. List transcribed by ChatGPT: 8557, 8438, 9539, 7063, 6827, 0859, 6793, 0738, 6835, 8093, 9047, 0439, 8196, 6693, 7394, 9480, 8398, 7637, 9629, 8068.

During tax season (in US), for security, you may optionally create a 5 digit pin. I wanted mine to be unaffiliated with any existing pin I have, and chose a 'random' number and wrote it down. A year later I repeated this (and had long since forgotten the previous pin), went to go write it in the same place, and saw that both 'random' numbers had the same first four digits. I now use a computer to choose random numbers because I no longer trust myself to be random.

I'm using correct-horce-battery-staple to fool those pesky kids with dictionaries.

l337 converter gives: c0rr3c7-h0r53-b4773ry-574pl3.

Veritasium says 37 is the most frequently-encountered number people pick between 1 and 100. I guess people subconsciously just want to be 1337.

1-2-3-4, that's amazing, I have the same combination on my luggage!

(sigh) 1-2-3-4-5? That's the stupidest combination I've ever heard of in my life! That's the kinda thing an idiot would have on his luggage!

Before reaching the bottom of the article, I was wondering about 19xx codes, given that I've heard many people using years, or month/day pairings for garage door codes and such.

I was glad to see those plotted out. I was also initially surprised that not a single 19xx pin made the top 20, but I suppose it makes sense considering that there are 100 different combinations of this code.
