A friend of mine had some Bitcoin on his phone a couple of years ago and he's lost that phone which stored the private keys on without any other backup. We can see his balance on the blockchain and he knows his password for the private keys. Is there a way of creating the private key from the bitcoin address and the known password?
he can get access to his account because these days the private keys are not really necessary when it come to accessing ones account but if sane questions are to be asked, i will like to know how he got to open his account and via what website or wallet application. that will be a take off point.
