4 ways:

One, reset user account password with Apple ID
There is a premise to using this method

such as a red box, this entry must be checked, otherwise the password cannot be reset using the Apple ID. (If you don't remember to check out, you can at least remember that when you first start OS X or a new Mac with OS X Lion or later, you go to the OS X Setup Assistant, which requires you to enter your Apple ID.) After you enter your Apple ID, in the Create your account stage, select the Allow my Apple ID to reset this user's password option. )
Well, here's how to do it:
If you incorrectly enter your account password three times in the login window, a message says, "If you forget your password, you can use your Apple ID to reset your password." Click the icon with an arrow in the circle to bring up the Reset Password dialog box. Enter your Apple ID and password, then click Reset Password to continue.
In the dialog box that informs you about the new keychain information that is displayed in the system, click OK.
Enter the new password, verify the password and password hint fields, then click Reset Password to continue.
Click "Continue login" to complete the login with the new password you just created.
Note: Changing the user account password will create a new keychain. The previous keychain still exists and can be accessed if you later remember the previous password.

You will see at least two accounts, the new administrator's account number and your original account number, the original account in the point, select Change Password. You do not have to have the original password to set up a new password directly.
