You've been hearing the advice for a couple of weeks now: You need to change the passwords on all of your accounts. They could have been compromised because of the Heartbleed bug.
And when you do that, come up with passwords that are hard to crack.
The folks at Bit9 estimate that a hacker can guess a password that is eight, all lower case characters in about 3.5 minutes. Change just one of those lowercase characters to uppercase and that can make a big difference.
"It doesn't have to be the first one or last one, it can be any uppercase character in there," said Bit9's Mike Viscuso. "And the time it takes to an attacker increases from three minutes to 15 hours. And if you have an uppercase character and a special character, like an @ or !, that goes to 70 days."
If you're like me, you have lots and lots of passwords. It might be time to get a password manager. Some of them are free. Load everything in and all you have to remember is one password.
