memorize it. they can't steal that from you. prove me wrong?
i considered this, though illness or injury could cause me to forget. Also, there are several mind reading technology patents filed in recent years.
Same with me today I memorize the code but after sometime I totally forgat it. And it happen to me many times, so whenever I create new account, I write it on a small notebook that I could understand, do not. Write the password itself make a line where in you will have a clue make a copy also in a paper then keep it in your wallet.
