These days, it’s increasingly affordable to build extremely powerful and fast password cracking tools that can try tens of millions of possible password combinations per second. It used to be the case that picking an alphanumeric password that was 8-10 characters in length was a pretty good practice. Some of the easiest-to-remember passwords aren’t words at all but collections of words that form a phrase or sentence, perhaps the opening sentence to your favorite novel, or the opening line to a good joke. Avoid using simple adjacent keyboard combinations: For example, “qwerty” and “asdzxc” and “123456” are horrible passwords and that are trivial to crack. If you must use dictionary words, try adding a numeral to them, as well as punctuation at the beginning or end of the word (or both!). Password-cracking tools freely available online often come with dictionary lists that will try thousands of common names and passwords. Do not use words that can be found in the dictionary. Do not choose passwords based upon details that may not be as confidential as you’d expect, such as your birth date, your Social Security or phone number, or names of family members. Don’t use easily guessed passwords, such as “password” or “user.” Do not use your network username as your password. Create unique passwords that that use a combination of words, numbers, symbols, and both upper- and lower-case letters. Take a moment to review these, and consider strengthening some of your passwords if they fall short. Here are a few tips for creating strong passwords.
