STUDY: Nearly 20 percent of bank account holders use same ATM PINs

11% of cardholders use PIN 1234

WEST PALM BEACH, Fla. - Is your ATM passcode really only yours? You may be surprised what a new study has found.

Nearly 27 percent of us may be using the same few PINs, according to researchers. That could be dangerous.

Research firm DataGenetics examined 3.4 million PINs and found that nearly 27 percent of us are actually using the same 20 codes.

"I'm very glad that my PIN is not on here," said Alyia Hollis, a West Palm Beach resident who was seeing the DataGenetics findings for the first time. "I keep a PIN that is only for me to know and me to find out," Hollis said.

"I would think that people would try to be more creative and not try to access their hard savings," said Lucia, a Fort Lauderdale resident.

You may already be able to guess the most common and therefore the worst ATM code: 1234.

What may be more surprising is that this study shows that nearly 11 percent of cardholders actually use that very PIN.

"That's ridiculous," said Hollis. "That's the first guess that someone would try to do is 1234."

Next in line after 1234, according to researchers, is the passcode 1111 and 0000.

By comparison, the dataset the website concluded that 8068 is the best pin. The researchers found only 25 occurrences out of the 3.4 million users (this equates to 0.0007percent), which is "far, far fewer than random distribution would predict, and five orders of magnitude behind the most popular choice." 

That's followed by 8093 (0.00089 percent) and 9629 (0.00095 percent). 

The website offers a warning to readers. Now that it has published that, historically,  8068  is (or was?) the least commonly used password 4-digit PIN, you shouldn't go out go out and change yours to this! Hackers can read, too.
