I have forgotten my admin password. What do I do?

If I use a disk to reinstall the operating system, will it erase everything?

Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

  • HT1752 I have forgotten my admin password and need to create another user

    I have forgotten my admin password and need to create another user. Have no disks to boot from!!

    You need an installer disc in order to reset an admin password. I don't know if the following will work on your system, but give it a try:
    You can also reset the password by printing out (or writing down) and carefully following these steps.
    First, find the short name of the admin user on the machine. The easiest way of doing this is by looking at what their directory is called in the Users folder.
    Now, start up the computer while holding down Cmd-S. It should boot into a command line. (If it doesn't, you may need to reset the firmware password, which is detailed elsewhere.)
    Type these exact lines:
    mount -uw /
    ifconfig lo0 up
    cd /var/db/netinfo
    netinfod -s local
    Now you'll need that short name. (You did write it down, didn't you?) Type "passwd", a space, and the short name of the admin. For example, if the admin was - rather prosaically - called "admin", you'd type "passwd admin".
    The computer will now prompt you to change the password for "admin" (or whatever the short name was). Go ahead and type a new password.
    Now, type:
    sync
    reboot
    and the machine will reboot. The admin password should now be changed.

  • HT5129 I have forgotten my ME password What do I do ?

    I have forgotten my ME password What do I do ?

    I have forgotten my ME password What do I do ?
    Do you need to sign into Mobile Me to recover your images? Then go to the page: "How to find your Apple ID password" and reset the password for the Apple ID that you used with MobileMe.
    But if you only want to dismiss the "Mobile Me has ended" warning alert, then press the "Learn more" button when this panel is shown, after you lauch iPhoto and then open the iPhoto "Preferences > Accounts" panel. Remove Mobile Me from the list of accounts.
    Afterwards open the System Preferences Mobile Me panel and sign out of Mobile Me.
    If this does not work, you may have to retry it after disconnecting from the Internet and launching iPhoto without an Internet connection.
    Regards
    Léonie

  • I have forgotten my iPhone password- what do I do?

    I have forgotten my iPhone password… what do I do?

    Either force the phone into recovery mode, as described here, & restore it:

    Or, login to iCloud.com, locate the phone, then erase it.
    Either method will remove the passcode.

  • I have forgotten my Master password , help !

    I have forgotten my Master password , what should I do , please be precise as I am barely computer literate .

    Please clarify if you are talking about the Master Password associated with FileVault, or your standard everyday login password.
    If you're talking about FileVault's Master Password it is possible to reset the it, but it still requires all users with FileVault-protected accounts to know their passwords. If a user has forgotten his or her login password, and you have forgotten the master password, there is no way to recover the user's data.
    If you forget the master password, you can reset it, but you must know the passwords for any accounts with FileVault enabled:
    1.
    As an administrator user, delete the master password keychain file (/Library/Keychains/FileVaultMaster.keychain). When the master password keychain is deleted, Mac OS X assumes that no master password is set yet.
    2.
    In Security preferences, set a new master password.
    3.
    Log in to each account that has FileVault turned on, and use Accounts preferences to reset the password for each account.
