I just had an idea. What if there is a tool which algorithms create a brain wallet password from the fingerprint (or from multiple fingerprints of the hand)? Every fingerprint is unique. Therefore every password created by the algos will be unique, too.
Thus, one would never run into the risk of losing his or her password anymore. Perhaps there is something already. However, I do not know it.
Wow, amazing idea. This could be an alternative to the security of every wallet bitcoin we have. This is going to get these new ones in the bitcoin: for we will not feel fear when saving bitcoin and will not get a suspicion.
