Reset Password When You don’t Know It

#1. Use Your Apple ID to Reset Admin Password on Mac

It could also be very useful when you do not have another admin account to reset your password. This feature that let you reset the password using Apple ID was first introduced in Mac OS X Lion ver 10.7. And remember, this method would only work if you had enabled this feature while setting up your Mac for the first time or later in the system preferences.

If you have ever created another account on your Mac or if you have shared it with someone else who might have created another account with administrative privilege then you are in luck. If you know the password for the other admin account you can use that account to reset the password for any account on your Mac. This feature was first introduced in Mac OS X 10.4. This method won’t help to them who just have one admin account, in that case you need to use recovery mode to reset the admin password. You can also use the default hidden system administrator account often called as root, to reset the password for another account only in case you remember the root password if you have ever dealt with it before. Follow the below steps to reset the password from recovery mode.

  1. In order to perform this action, you need to make sure that you are logged into the admin account you know the password for and the other account whose password is to be reset is logged out.

Using this method or any other method listed below will cause to lose all the saved passwords for different websites and applications such as Mail, iMessage, FaceTime, Outlook, Skype, etc. These passwords are stored in keychain which by default has the same password as your login password if you did not ever change it. Forgive me for keychain as there is nothing you can do to recover it because its encrypted and even Apple can’t recover them. The biggest problem that cripples you the most is the keychain pop up that keeps showing you after resetting the user account password. You will have to reset the Login Keychain to fix that error. You can also create a new Keychain when you login with the new password for the first time. It will ask to update the KeyChain password or create a new one. Select create New KeyChain. Updating the KeyChain password isn’t an option for you because you don’t remember your old password. If all the above method does not work, don’t despair as help is on the way.
