Don’t Use These 4-Digit Pins on Your Smart Phones

Quote:
A review of more than 200,000 4-digit PINs used on mobile phones revealed the following as the most common (in order):

1234 (used by more than 4% of the sample group)<
0000
2580 (straight down the middle of the keypad)<
1111
5555
5683 (spells LOVE)
0852 (straight up the middle of the keypad)
2222
1212
1998

The 10 most frequently used PINs represent more than 14% of the total sampled. Thus, with this distribution of PINs, you have a 1 in 7 chance of guessing the correct one in 10 tries.

Years are always popular when coming up with a 4-digit PIN (see number 10 above). So, birth year, graduation year, etc. would also be a good guess if these are known

Regardless, it's a very good idea to recommend people NOT use these particular PINs (at least the first 9 plus predictable years).


It's a bit misleading since it only represents 4-digit PINs. The best recommendation is to use a longer PIN.



It does make me wonder about ATM PINs, though...

@DrewDad,
Thanks for the info. Mine is ok. I use 9999 which isn't in the list Smile

(just kidding, I don't really use 9999)

We get our ATM pins sealed here, they are randomly chosen by ... a computer, I guess. (And hard to remember - thanks for helping!)
