I used be lead dev for a big streaming site with >2m users and, well, no judgment here please, but the passwords were plaintext in the database. So me and another dev ran a SQL script to see what the most common were. #1 was trustno1 #2 was password #3 was 1234 We had no password rules either, so IIRC you could have a 1-char password.

I always like Brian Kernighan's password "/.,/.," [1]. If you're going for a stupid password anyway might as well make is easy to type. "password" is not particularly nice to type; I wonder why "asdf" is not generally more popular.

Whenever I'm asked for a 4 digit PIN: `echo $[RANDOM%10000]`

I'll remember to prioritise 0000 to 2767 for your PINs, then.

Just so you can see the bias to early numbers in the distribution:

    for i in $(seq 1000000); do
        echo $[RANDOM%10000]; 
    done | sort -n | uniq -c | sort -rn | gnuplot -e "set terminal dumb; set xtics 1000; plot '

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.

Majority don’t use PIN anymore - just tap card/phone.

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. https://youtu.be/U6fxkOL83V4

Not that many futurama fans in those data breaches ...

So many silly scenes like this. I want to re-watch Futurama because last time I watched it was as a teenager, so I'm sure I missed many of subtle jokes.

Not sure how this is handled in Switzerland, and I don't have good data on this, but I'd say a lot of people in Europe have at least a debit and a credit card with a PIN each. Also nothing says you can't use the same PIN for multiple cards; they're essentially the same security domain anyway ("a piece of plastic in your wallet") — most people don't have "more" and "less" trustworthy cards…

All cards have randomized pins and can later be changed.

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.

2000 is #7, 2001 is #19. Guess what they mean. Oh wait, it was in 2012.

asdf and qwerty were up there in the top 10 I think. This was just prior to the days of SQL injection and I'm 100% sure you could have erased our entire production DB with a really "strong" password.

One of my credit unions gives out (randomized) five digit pins (although they say if you use an atm that only accepts four digit pins, the first four is enough). My other credit union only does four digits. I think remembering one 6-digit PIN would be fine, but in the US, it's common to have many banking relationships. If I needed a pin for every credit card, I'd have to write them on the cards or set them all the sa…

Why not have the same password for all your banking accounts then? But everyone says not to reuse passwords.

If someone takes your wallet, it'd be nice if they don't drain all the accounts based on figuring out the pin of one card?
