On the internet, every password should be unique to each site that is storing your username and password. This protects you on other sites if one site has your password stolen. A password manager is a preferred method of securing all your unique passwords with one master password. However, many people have trust or cost issues using one of these services. A mnemonic password scheme is a simple alternative to remembering unique passwords that require no software.
Here is a simple one (but not the one I use).
Start with a base password “Iagl” – remember by “I am good looking”
Let’s say you need a password for Google. Take the first two letters and make them capital “GO” but let’s make them the first and last character of the password.
Now let’s add a number. Google has 6 letters so let’s pick “6”. So my password for Google is “GIagl6O” .
My password for Facebook is “FIagl8A”.
A few sites will require a special character (like a “%” or “&” but not all support these types of characters in passwords. For those that require one, simply add one to the end and if your default password is wrong, you can add the special character.
Should my Facebook password be stolen, it is unlikely even a human can guess my Google password (unless they read this article).
