I originally posted this as a response to a discussion on this issue on another site and it seemed to generate a positive response, so since the Loungers here at WindowsSecrets have been so incredibly helpful to me with my computer issues, I thought I’d post this idea here in case it’s helpful to anyone.
Like many others who’ve written or posted on various sites with regard to passwords, I prefer LastPass (or Keepass) to keep my passwords safe, but if I need to write some down for any reason, I can do so with no security concerns. When I create passwords, remembering strings of random characters is way beyond the capacity of my aging brain, so I find it easier to just create little blocks of characters that I can easily remember and give them code names that will mean nothing to anyone but me.
For example, let’s say that your sister’s initials are PDG, born on the 27th of April, and your brother’s initials are MJD, born on the 6th of May, and that you all grew up at 673 Clarkson St. Your password could then be pdG27673mjD06. Your written-down code for that could be “SisClarksonBro” (without the quotes), or even SClarksonB, if that’s all you need to remember what it stands for.
Using this procedure (though you can easily invent your own – and should!), you could add blocks for Dad and Mom, your children or grandchildren, your pets, or anyone else you choose. However, if you want to get extra uses out of fewer blocks, especially for lower importance sites where a security breach wouldn’t be life-destroying, you could, using this system, keep the “Sis” and “Bro” blocks, but vary the middle one (or the first or last, as you choose). For example, if your best friend Mike lives on Dogbreath Drive, your password could be pdG27DogbreathmjD06 and your written code for that could be SisMikeStBro or SMikeStB. If you do a series of these and can remember the constant bits, all you have to write down is your middle block (or whichever block you vary), so your written-down password list would look like:
Site 1: Clarkson
Site 2: MikeSt
(Etc.)
Also, please remember that you’re not limited to only three blocks in a password (longer is always better), nor do you have to only vary one block. It’s important to make up your own system [this is not the one I use, which is of course Top Secret, but just an example I made up for this post], with the key point being to use character blocks you can easily remember because they have meaning to you, and for which you can have a simple code that will jog your memory, but no one else’s.
There you have it, a way to keep a written-down list of password codes that are meaningful only to you and will be utterly useless to anyone who might find your list.
Hope that helps.
