One of the challenges of living online -- which nearly all of us do more and more -- is that we have passwords for everything. Facebook, Gmail, Hotmail, Bank of America, Twitter, Amazon, Overstock, eBay, PayPal...the list goes on and on.
For E-commerce merchants there is a whole new layer of complexity: passwords necessary to run an online store and keep business and customer data safe.
Let's face it -- it's hard to remember a unique username and password (i.e. "credentials") for each site we use. As a result, people often do one of two foolish things:
"But- but- I can't be expected to remember an obscure, unique password for everything!" you protest. No you can't. And neither can most people. So here is a handy-dandy guide to creating obscure, unique, hard-to-guess passwords.
Many web sites tell you to choose a password "easy for you to remember but hard for others to guess" Here's how:
Let's say you choose perhaps the most memorable line written by Percy Bysshe Shelley in perhaps the greatest English language poem ever, Ozymandias:
Look on my works, ye Mighty, and despair!
"Look on my works, ye Mighty, and despair!" becomes lomwymad
Now, if you told a friend "My password is l-o-m-w-y-m-a-d or 'lahm-wee-mad,'" there is a very slim chance she would remember it. That's a password that is difficult to guess. But if you simply say in your head whilst you type, "Look on my works ye mighty and despair" you'll enter your password correctly every time.
Since this isn't really a "word" it's not technically a "password" but rather a much more sophisticated-sounding "passphrase."
Solution? Add capitalization. Any word that is capitalized would also be capitalized in your passphrase so:
lomwymad becomes LomwyMad
Better, right? Now, add punctuation. And, optionally, if your memorable phrase contains words like "at," "and," "to," or "too" you can switch them out for more-secure symbols like "@" "&" and "2" -- so now your passphrase is
Lomw,yM,&d!
Now that's secure!
You can also swap out letters for unrelated numbers or symbols. For example, the letter "o" could be swapped out with the number "0", the letter "s" could be swapped out with the symbol "$", the number 1 or the letter "l" could be swapped out with an exclamation point "!", etc.
Why bother adding special characters like this? Check out this chart from Internet standards expert John Pozadzides in this post: a password hacking software could crack a password of 8 random lowercase letters in about 2 and a half days. If that same 8 character password includes special characters it takes much longer: 2 centuries.
There are a few options and variations here.
Using unique, obscure passwords for all your credentials will keep you, and your sensitive data much more secure.
