There is no 'password' for Minecraft, in any version. The password is user specific; each user makes their own password. You either need to buy Minecraft and in doing so create a password, or play offline. Note - it is illegal to have copies of Minecraft, but if you have lost your password, there should be a way to change it or find it on the Minecraft official website.
You can well kinda, First download minecraft to your computer after playing the demo, then enter your username but not your password after opening minecraft that you downloaded, when it says: can't login click play offline, and there you go but you can't play multiplayer.
There is no protected password to install minecraft but you do need an account created on the site and then pay for the game to play it
Minecraft is all about the account you made, you can log into that account on any computer, you are not forced to play it only on the computer that you purchased it on.
Stealing someone's account is not allowed by Minecraft. You can buy the game and get your own account to play.
