We probably all agree that passphrases can be easier to remember than complex, random passwords. IhaveABIG2013truck! can be memorized in just a couple of minutes whereas Ih*^29xB@@!dude would take a lot longer to commit to memory. This isn’t to say that passphrases can’t also be difficult to remember.
Athletes, artists, musicians, craftsmen – anyone who develops a particular manual skill – rely on muscle memory to a greater or lesser extent. As a musician, I know that repetitive practice of scale patterns, chords, picking patterns and melodic riffs trains the muscles in my fingers to “remember” those patterns. At first, I feel awkward and perform slowly, but after a while, the patterns come second nature and take little thought to perform.
You can do the same thing with passphrases and passwords. In fact, the best typists usually don’t think about what they are typing: the key patterns for whole words are trained into the muscle memory of their fingers.
An innovative approach to utilizing muscle memory is to choose passwords and passphrases that alternate between left hand and right hand on the keyboard. The rhythm 0f going back and forth will soon be ingrained into your fingers. This requires some knowledge of touch typing, but don’t worry, you can get familiar enough with it in just a few short lessons on line. Here’s something that may help you. The image shows the “home” keys and you can probably easily figure out which hand goes with which keys.
A random password like A*#9tU is a left, right, left, right pattern. For passphrases, there are hundreds of words that alternate in this manner. Below is a sampling from a list called lrwords.txt that you can find here:
Add in some numbers or special characters that alternate hands and you’ve got the advantage of unusual passphrases that use both your mental and physical memory. How about fiendish1927emblem? Easily memorized and has a nice rhythm on the keyboard. Type it a few times and it’s not likely you’ll forget it.
