Protect your computer with strong passwords
Rating: 2.5 / 5 (18 votes)

Strong password requirements (using upper and lower cases, at least one number and maybe a special character) cause a lot of frustration for computer users. There is however, a way to manage your passwords without sacrificing security for convenience and the best part is the solution is available for free.

Let's start at the beginning: the computer's login screen.

Whether you are running Windows, Mac, Linux or any of the other operating systems out there, when the system boots up it will look for a password. Now sure, I know what some of you are thinking, "I don't have to enter a password when my machine boots up so you must be wrong."

Well, that isn't entirely true, it's just that most machines will give the user the ability to either auto logon or not require a password at all at boot up. This is one of those instances where people will sacrifice security for convenience. People don't want to be bothered entering their password every time, so the system gets set up without it.

Sure it's convenient, but the problem is now anyone who sits in front of your machine and turns it on will be able to get in and have access to all your stuff.

Many people choose to go this route thinking that "Hey, I'm the only one who uses this machine so I don't need it asking for a password every time" but if we are talking about a laptop (which is portable) that can be a disaster waiting to happen if it ever gets lost or stolen.

If it's a desktop machine the argument seems a little more valid, but it won't protect you if there is a break in or some other unauthorized user gains access to your machine (either physically or gets in through the internet).

The fact of the matter is if your machine is connected to a network then there should be a password in place to protect your files.

The next area where people sacrifice security is in password strength.

Weak passwords may be easy to remember, but they are often short "dictionary" words that can be cracked in a matter of minutes by any of the available password cracking utilities that are out there.

Passwords such as "god," "monkey" or any other word found in the dictionary may be short and easy to remember but they are also the first things these password cracking utilities will try.

That's why many sites (and programs) will insist on including upper and lower cases, some numbers and even a special character or two.

"MonKey!387" is a hell of a lot harder for someone to crack than just the word "monkey." Sure, it may be a little more inconvenient but using a weak password will just give you a false sense of security.

The next shortcut people take is in using one password for everything. The reasoning is "well, I can't remember a different password for everything so I just use the same one everywhere I go and never have a problem."

I will be the first to admit, using the same password for the windows login, email, etc. is convenient, but a problem can arise if your password does get cracked. It's common practice for hackers (when they discover someone's user name and password) to try that same username and password pair everywhere.

Again, there are tools out there that will allow someone to enter a username and password and the program then goes and tries them on hundreds of sites (such as AOL and Facebook) and then provides the hacker a list of all the sites where the password works.

Using the same password everywhere is one of the ways hackers are able to take over all of the services that you use. It may be a bit inconvenient, but using a different password for every site is a lot safer than using one password everywhere.

Earlier in this column I mentioned there is a free solution out there that solves these issues.

Open your browser and pull up www.keepass.com. Keepass is a free (open source) program that will allow you to store and manage all of your passwords in one place so you don't have to rely on post it notes all over your desk.

Use Keepass to create unique strong passwords for all of your sites and you won't need to sacrifice security for convenience.
