How safe are the passwords you use for your computer? It’s important to choose passwords that are easy to remember, but not easy for someone to guess or discover using hacking software. Because this is such a tough balance to maintain I thought I’d spill the secret on two of my password selection secrets. To be effective, passwords should contain upper and lower case characters, contain special characters, contain letters and numbers, and be longer than eight characters in length. The longer the password, the tougher it will be to crack.
My first trick is for a password that isn’t for anything critical. I’ll let you decide what that is, but I would define non-critical as any password that, if cracked, would be a annoying but wouldn’t destroy your financial or personal life. For this type of non-critical password, you want it to be something very easy to remember, but hard for someone to guess or find in your Blog entries. Most of us have an old phone number we still remember from our childhood floating around our noggin. The trick is to never use a number that could be associated directly with you through public records. For instance, you could use a phone number from when you were a child, which would have been registered to your parents. You could use the phone number of a childhood friend, a church, or even one you saw on TV. Just make sure it’s not one that could ever be associated with you. For extra security you should add a few characters to the password and/or include the area code. For instance, “Betty_9015551234″, “8675309_Jenny”, or “oldWork_5551234″. The problem with this method is that you have a limited supply of old info like this. If you need to change the password often, you might find yourself struggling to come up with a new password.
This next method I use regularly. This is secure and easy to remember and I use a similar method for my bank, email, and administrator passwords. It allows me to create an infinite list of passwords without ever fearing that I’ll forget one. Instead of remembering a password, you remember a format for the password. Then you can make the password something simple and familiar, but the format makes it nearly impossible to guess. For instance, I use a date method similar to “year_day_month”. Today’s date would be written like this, “2009_26_April”. This password is alpha-numeric, upper-lower case, and longer than eight characters. If I pick dates that I know, I’ll always know the password. What was the date when I got my first car? When was the battle of the Alamo? What was the date of the Chernobyl disaster? What date did I receive my first kiss? All of those dates are either easy to look up online, or easy to remember. So, if I would happen to forget the exact password of, “1969_20_July”, I’ll know it was the date of the moon landing, which I’ll be able to look up online and then I’ll immediately know my password. If you format all dates in the same way, then you just need to remember your format, not the actual password. More examples using dates from space exploration, “1957_4_Oct” (Sputnik), “1962_20_Feb” (John Glenn’s first orbit), “1977_18_February” (first space shuttle flight). Just make sure to never reveal your format to anyone. You could even tell them that your password is your own birthday, but figuring it out might be really tough. Especially if you add more complexity by spelling out one digit as, “196nine_20_July”. It’s much easier to remember a format and a concept, like “moon landing” or “dad’s birthday”, than a string of characters.
The important thing to remember is that your personal information needs to be protected, which means that your password needs to be more complex than, “123″. Using a special format allows you to keep your password complex and secure, while still keeping it easy to remember.
