You can pen and paper store a password if you have a system.
Here's one. Password is combination of a word, with numbers and symbols. Then you encode it for yourself.
"pizzabyTigger88" is what is written
To me that means the password is "pepper93))oni"
Pizza = pepper oni
byTigger = the year my cat Tigger was born
88 = )) - caps and add a key
And only I know the last 3 letters of the major word come after the other keys.
Do this for yourself. Easier than most codes, only decodeable by you and those in the know.
