We have become bombarded with usernames and passwords. What does one do with all of them? More importantly, what is the best strategy for creating new passwords? I’ve learned the hard way, so I am passing along what might help you to prevent a problem or worse.

Make passwords long and complex. An example is k7*S+4c2$8R. Strength checkers, such as passwordmeter.com, will score a password on a scale of 1 to 100. I would not enter a real password, but you can try something similar by substituting like characters. Short and simple passwords, such as “sunnyday” are easy to crack.

In 2011, according to Wikipedia, commercially available products could test up to 2.8 billion passwords a second on a standard desktop computer. This means it’s possible to crack an all upper or lower case password of 10 characters in one day. Today’s computing is much faster.

Using the same password for multiple accounts is ill-advised. Make each one different, long, and complex. Managing all them is another issue. Password managers are available, although I have not used any of them, partly because our IT guy is not a fan of ’em. Those that are highly ranked by PC Magazine are Dashline 4 and LastPass 4.0 Premium.

Bottom line: do not take passwords lightly. Make them complex by mixing upper and lower case letters, numbers, and odd characters such as @#$^()=?><!~%*+&. And, make them long. For each character you add, the strength of the password improves exponentially. (It’s not linear.) Having an account hacked due to a short and simple password can make your life miserable, and it can be expensive too.
