By now you should know that "123456" is not a smart password.

If you’re still using a weak password like that gaping sieve -- and haven’t even changed all your online passwords since news of the wretched Heartbleed SSL vulnerability broke -- you’re hacker bait.

Failing to create super strong online passwords leaves the keys to your banking, credit card, social media, email and more -- basically your whole life -- within dangerous reach of hackers’ grubbing hands.

You could either a) do nothing and take your chances (which we strongly advise against) or b) take the 10 or so pain-in-the-brain minutes to build an army of strong passwords and sleep well at night again.

What are strong passwords? They’re long. We’re talking 8 to 15 characters. They’re complicated. Think alphanumeric gibberish. And they take years to crack. Sadly, no single password is guaranteed to be 100 percent hack-proof. That said, killer password production is a bit of a fine art. One that’s not impossible to master, though, with the right tips and tricks up your sleeve.  

Once you do switch up your passwords (come on, just do it already!), don’t sit back and get comfortable. Be vigilant. Play a proactive role in protecting your private online information by regularly changing them, optimally as often as you would a Brita filter, about every six to eight weeks. Or, if you’re really motivated and have the memory of an elephant, alter them every week.
