Question from Andie J.: My boyfriend and I have a bet that’s riding on your answer to this question:
Is a six digit PIN really all that more secure than a four digit PIN?
It don’t seem like just two digits could make that much difference. He says it makes a big difference in making a phone harder to break into.
So who’s right?
If you agree with me he has to take me out to dinner. If you agree with him I have to cook him a steak dinner with all the fixin’s. We both subscribe to your blog and we’ll trust your opinion.
Rick’s answer: I hate to have to tell you this Andie, but you’re gonna have to to prepare that steak dinner for your boyfriend.
A six digit PIN isn’t just slightly more secure than a four digit pin. It’s actually a LOT more secure. And that isn’t an opinion, it’s a statistical fact. Here’s why…
A four digit PIN has 10,000 possible combinations. I know that sounds pretty impressive, but it’s actually quite easy to break using various electronic methods.
However, a six digit pin has a whopping 1 million possible combinations. And that of course makes it LOT harder to break (and a lot more time consuming) using those same methods.
Bottom line: If you secure a device (or an online account for that matter) with a PIN, using a six digit PIN will provide a LOT more protection than selecting a pin with just four digits.
