Passwords are currently the most common form of access control for access to your PC, the applications and files, and the Internet. Since it serves as the key to your identity, your password should remain a secret known only to you. There are several rules that apply to having a good password. Be creative and donít use dates and names that can be easily guessed. Have more than one password and use different ones for different Web sites. When you use one password and itís compromised, that means that your access to all the Web sites where itís listed is compromised. Donít tell people what your password is and definitely donít write it down and post it on you computer monitor. Furthermore, while your ISP may need to know your password to access your account and fix a problem, be wary. If youíve called the ISP and are speaking with a representative, itís pretty much a sure thing theyíre a legitimate representative. However, if you receive a telephone call, even if it sounds official, refuse to divulge your password. Many scams are perpetrated in this manner, and itís better never to give it out until youíve investigated who the requesting party is and why theyíre requesting it.
