OS X Mavericks: Reset a login password
Sometimes a user’s login password needs to be reset—for example, when the user has forgotten the login password and can’t use a password hint to remember it.
When a user’s login password is reset, a new default keychain is created to store the user’s passwords. For more information about keychain passwords, see:
Reset your login password using your Apple ID
You can use your Apple ID to reset your login password only if “Allow user to reset password using Apple ID” is selected in Users & Groups preferences.
- If FileVault is turned on, open Security & Privacy preferences and turn it off. FileVault must be off to use your Apple ID to reset your login password.
- Log in to your account. In the login window, click the question mark in the password field, then click the arrow in the dialog that appears.
- Enter an Apple ID and password, then click Reset Password.
