Good Password Advice is Never Wasted

Ken Harthun Ken Harthun Profile: Ken Harthun

So, let me repeat myself. People tell me everyday about how this kind of advice helps them, so here it is again.

A little Alliteration is good for writing effect every now and then; why not apply this to passwords? I don’t mean to write out an alliterative phrase and turn it into a password or passphrase (though you could, I guess); what I mean is to use a pattern that makes it easy for you to remember the password, but still results in a very strong, un-guessable one. Here’s an example of a very strong password: 19[-[Phrase]-]60.

This one is very weak: %6*Some*Phrase*6%. Can you see why? Too many repetitions of characters. Change it slightly, %6!Some*Phrase!6%, and it becomes very strong.

The trick is to come up with a pattern that means something to you. By no means should you use the patterns I suggest—use something that will be easy for you to remember.

I’ll leave it to you to analyze the two examples and let you come up with your own. Remember, the bad guys read these blogs, too.

You can mosey over to the Password Meter page at Ask the Geek to check the patterns/passwords you come up with. That’s the best password meter I’ve ever seen, bar none.
