Do you think MyEtherWallet is safe ? Coz its PK feature feels unsafe to me , you could just randomly type numbers & letters (a-f , 0-9) and you'll enter a wallet ..
My ether wallet can be very safe if you know how to use it, what you are saying does not make sense, even if you could type the exact password by chance you will still need to have the keystore that you receive when you first login into your account, so not only you need the password you need a file, if a hacker is able to get both of those that is no longer the problem of my ether wallet but a problem with the way you manage your own security.
