“PLEASE enter your password.” For many people worldwide, these words flashing across a computer screen are part and parcel of everyday life. Whether you are logging on to your personal computer, switching on your mobile telephone, using a credit card, or disarming a door-security system, passwords, or PINs (personal identification numbers), jealously guard access to numerous regular operations.
How can you choose ones that are sufficiently complicated to be secure yet are simple enough to remember ?
There are basic guidelines to bear in mind
First, the don’ts. Don’t use as a password your name or that of a member of your family, even in modified form. Also avoid use of the number on your license plate, your telephone number, your Social Security number, or your address. Such information can easily be obtained by a determined hacker.
In addition, if possible, don’t use passwords made up entirely of letters or digits. A relatively simple computer program can crack such a code quickly. Finally, do not use a word that can be found in any dictionary, even a foreign-language one. Huge lists are available that contain words, place names, and proper names from all languages. Programs can test for variations of these words, such as if they are spelled backward, capitalized, or combined.
So, what kinds of passwords should be used ?
Usually ones that have a minimum of six to eight characters and that have a mixture of upper- and lower-case letters, digits, and punctuation symbols. How difficult is it to crack such a combination of characters? One source says that “a machine that could try one million passwords per second . . . would require, on the average, over one hundred years.”
How can you choose a combination that is easy to remember ?
Some suggest that you take the title of a favorite book or film or a line from a song or poem and use the first letter from each word as your password, adding capital letters, punctuation, or other characters. For example, “to be or not to be” could become “2B/not2B.” You could even take a Bible reference and use this as your password. Thus 1 Chronicles 9:27 might become “1Chr9:27.”
Other suggestions include alternating consonants with one or two vowels to form a nonsensical word that is pronounceable. For example, “QuiMSoPy” or “WotyRuba.” Or one could take two short words and link them with a punctuation character, such as “High?Bug” or “Song;Tree.”
Although not all passwords require the same degree of security and some programs may not accept certain characters or recognize capital letters, taking into account the suggestions outlined above can help you to protect important information from unwanted intruders. Remember, too, the importance of changing your passwords regularly. Just a final comment: Whatever passwords you decide to use, don’t pick any of the examples given above
