What if your home or car lock used one of those simple, one-notch skeleton keys like you see for unlocking treasure chests in movies? It would offer pathetic protection that can be easily circumvented. That would be dumb.
Why is it, then, that so many people do essentially the same thing when it comes to protecting sensitive and confidential data? The tendency for users to choose weak passwords is well-documented, and has been demonstrated time and time again when breaches expose passwords and we get to see just how silly most of them are.
Unfortunately, smartphone PINs don’t appear to be any better. With more than 200,000 PINs to analyze, Daniel Amitay has compiled a list of the top 10 most used. Sadly, “1234” tops the list, followed by such complex PINs as “0000”, “2580”, “1111”, and “5555”.
You may as well not bother setting a PIN.
