August 24, 2005 Head Lock Even your brain has its limits. You can store only a certain number of passwords there before one just falls out. You've got the ATM, and the computer login, Voicemail. Email. Gmail. Upper and lower case. No letters. Letters and numbers. Numbers in the middle. It's a lot to keep track of. And the most unforgiving of all: the combination lock. All numbers. No security questions. At least until WordLock. WordLock works by the idea that words are easier to remember than numbers. Instead of inputing a number that you're bound to forget — say, your girlfriend's birthday — you can put in her name. (Forget her name and you'll be looking at another lock — the one on her door). Like most locks, you can reset the password at will. And you've got over a thousand four- or five-letter words to choose from. The downside: What's easier for you to remember is easier for thieves too. You might want to look both ways to see who's trying to peer over your shoulder before clicking onto your correct combo. Or try a non-word letter combo. With five rings and ten letters per ring, you're looking at a cool 100,000 possible letter combinations. WordLock is available for $5.98 at Staples.
