How to build better passwords without losing your mind

No password is perfect, but you can build a better password with these simple tips.

Your e-mail password is your last line of defense when it comes to online privacy and security; if a hacker cracks that, they could potentially reset the passwords of and gain access to your social networks, your bank account and even your identity by taking advantage of the ubiquitous "I Forgot My Password" button.

It's tempting to use the same password for all of your online accounts, but doing so renders every account vulnerable if any one of them gets hacked. But given some recent massive security breaches, now's a good time to update your passwords and make sure each is unique.

There are a few great password management programs like KeePass that will store all of your passwords in one encrypted database and allow you to access them with one master password, allowing you to carry every password you'll ever need on a single thumb drive. A multi-platform password manager with browser support like LastPass is even easier to use because it will automatically sync between different computers and browsers, letting you access your encrypted database from any device, though you sacrifice the security of keeping your password list confined to a single hard drive.

Using a password manager is a great way to improve your personal security online, but it's not perfect; the perfect password is the one you never write down, a unique string of letters, numbers and symbols that not even you know until the moment you enter it. That may be beyond our grasp, but you can get awful close by using a few simple mnemonic tricks.

One Password To Rule Them All

It's actually fairly easy to create strong, unique passwords by following a few simple rules. First, we need a password "base" with a mix of upper and lower case letters, numbers and even a symbol or two to spice things up. Pick a phrase that will be easy to remember, and feel free to be as creative as you like. For simplicity's sake I'm going to use one of my favorite dishes, chicken adobo, as our example.

Make sure your passphrase is at least eight characters and avoid obviously memorable topics like proper names, birthdays and hometowns. You should also avoid picking a single word and changing some of its characters to symbols -- hacker tools are sophisticated enough to foil that trick. Go for a passphrase -- multiple words strung together -- rather than a password; this makes it harder for hackers working to crack your password by trying every word in the dictionary.

Now that we've picked a passphrase, we need to mash that phrase into a single string (chickenadobo), then sprinkle in a few capital letters that are simple to remember (ChickenAdobo). Next, let's pepper our password base with a few random characters to keep things interesting (Ch!cken@dob0).

Now that we have our base password, we're going to memorize and use it as a skeleton key that will unlock our account on any Website as long as we hold fast to a few simple rules. To create the strongest password possible, we're going to invent a simple naming pattern as a mnemonic device that will help us generate a unique password for every Website we visit.

For example, let's say I decided to always use the first and fourth letter of a Website's domain name in the middle of my passphrase, capitalizing the former while leaving the latter lower-case. That means my Facebook.com account would have the unique password Ch!ckenFe@dob0, while my about.me account would require the password Ch!ckenAu@dob0.

See the pattern? Make up a something similar and you'll have a unique alphanumeric password for every website you visit, one that's easy to remember but nearly impossible for hackers to figure out. No password is perfect, but knowing your own unique passphrase and a few mnemonic tricks will go a long way towards keeping your online privacy intact.

STYLISTIC Q702

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
