How do I reset master password in OS X 10.7 Lion?

I have recently found out that my master password is not what I thought it was!
I am currently running OS X 10.7 Lion and would like to reset my master password.
There are two user accounts on the Mac - one being mine (administrator) and the other my sons (managed).
I know both account passwords but not the master password.
How can I reset it???
Thanks for your help in advance. :-)

You are looking in your user's library - you need to be in the system library as follows.
Open a new finder window and hit Shift-Command-C. (This takes you straight to the hard disk)
Then select: Macintosh HD > Library > Keychains.
          There should be a file called 'FileVaultMaster.keychain'.
Delete this file.
Then open: System Preferences > Users & Groups.
Click the padlock in the bottom-left of the window and type in your user password.
Then click the cog icon at the bottom-right of the list of users.
Now click 'Set Master Password' and create your new master password.

  • How do I reset Master Password?

    A few years ago I set a master password.  I know the master password but would like to change it.
    I've read a few articles and it says to do this via System Preferences/Security/File Vault; however, when I get to File Vault, the master password info/screen/area is not there.
    I am running Mac OS X Lion 10.7.3 (11D50b)
    Can anyone help me do this?  I can't figure out what I'm doing wrong.
    Thanks.

    Hello,
    I have tried a number of these topics to the left prior to posting the question.  I think the problem is that while I can change my administrator's password via Accounts, I can't seem to access/find the area for a Master Password as it is not in the FileVault area.  I'm just wondering if there is another area to access where the Master Password is set.
    Thanks.

    how do I reset my password if I don't know it ?

    Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
    When the OS X Utilities screen appears, select Utilities ▹ Terminal from the menu bar.
    In the Terminal window, type this:
    resetpassword
    That's one word with no spaces. Then press return. A Reset Password window opens.
    Select your boot volume if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Follow the prompts to reset the password. It's safest to choose a password that includes only the characters a-z, A-Z, and 0-9.
    Select  ▹ Restart from the menu bar.
    You should now be able to log in with the new password, but you won't be able to unlock the Keychain. If you've forgotten the Keychain password (which is ordinarily the same as your login password), there's no way to recover it. You’ll need to reset your keychain in the preferences of the Keychain Access application.
