Could you have one of the worst PINs on your debit or credit card? There are some common PINs that too many people are using and it could be putting your bank account at risk.
That little four digit number that you use at the cash machine may be more common than you think. While there are 10,000 possible combinations of the digits 0-9, many of those codes end up to be the same.
"It's got to be easy or I'll forget it," Consumer Randy Howey said.
"We would encourage them to use something unique. Don't just use a generic 0000 kind of PIN number," Joey Rotert of Sioux Falls Federal Credit Union said.
But the research firm DataGenetics gathered 3.4 million PINs and found that nearly 27 percent of us are actually using the same 20 codes.
1234 is actually the worst PIN you can be using, but in the study of cardholders, 11 percent of cardholders were using those very numbers. The next in line were 1111 and 0000.
Angela: If I told you 1,2,3,4 is the most common number would that surprise you?
Renee Umland: Yeah actually because it's so simple you would think that would be the first think you'd try, but maybe people are thinking it's so simple, nobody will think to do that".
But you don't want to have one of the 20 worst PIN numbers.
"And the top 20, the opportunity for hackers to go out and just guess the top 20 and 20 percent of those PIN numbers are going to be correct? That's crazy," Rotert said.
If you've got one of the most common PINs, it's time to change it up.
"But my PIN numbers are complex, so I'm not worried someone is going to hack it up," Consumer Murali Gali said.
The least used PIN in the research was 8068 used just 25 times in 3.4 million. But now that that information is out there, you probably don't want to use that combination either.
