The password of your macOS user account is also known as your login password. It's the password that you use to log in to your Mac and make certain changes, such as installing software.

Change your password

If you know your password and can use it to log in to your account, you can change your password in Users & Groups preferences:

Choose System Preferences from the Apple menu, then click Users & Groups.
Select your user name from the list of users.
Click the Change Password button, then follow the onscreen instructions.

Reset your password

If you don't remember your password, or it isn't working, you might be able to reset it using one of the methods described below. But first try these simpler solutions:

Make sure that you're typing the correct uppercase or lowercase characters. If your keyboard has Caps Lock turned on, the password field shows a Caps Lock symbol .
If the password field shows a question mark, click it to display a password hint that might help you to remember.
Try to log in without a password. If that works, you can then add a password by following the steps to change your password.
Try to log in with the Apple ID password that you use for iCloud. If you just changed that password and the new password isn't working, try the old password first. If that works, you should be able to use the new password from then on.

Press and hold the power button until your Mac turns off.
Press the power button again to turn on your Mac.

When done, click Restart.

Create a new login keychain, if necessary

After resetting your password and logging back in to your account, you might see an alert that the system was unable to unlock your login keychain. This is expected, because the passwords for your user account and login keychain no longer match. Just click the Create New Keychain button in the alert.

If you didn't see an alert about your login keychain, or you see other messages asking for your old password, reset your keychain manually:

Open Keychain Access, which is in the Utilities folder of your Applications folder.
Choose Preferences from the Keychain Access menu, then click the Reset My Default Keychain button in the preferences window. After you enter your new password, Keychain Access creates an empty login keychain with no password. Click OK to confirm.
If you don't see a Reset My Default keychain button, close the preferences window and select the “login” keychain from the left side of the Keychain Access window. Press the Delete key, then click Delete References.
Choose Log Out from the Apple menu to return to the login screen.
Log in to your account using your new password. Your account password and login keychain password now match again.

If you still can't log in with your password, contact Apple Support for help.
