Change the login password on Mac
It’s important to change your login password from time to time to protect your privacy.
Note: Your login password is the password you enter to unlock your Mac when you turn it on or wake it from sleep. It is not your Apple ID password, which gives you access to the iTunes Store, App Store, Apple Books, iCloud and other Apple services.
On your Mac, choose Apple menu > System Settings, then click Users & Groups in the sidebar. (You may need to scroll down.)
If you’ve forgotten your login password and can’t log in to your Mac, see the Apple Support article If you forgot your Mac login password.
Click the Info button next to your username on the right.
Enter your current password in the Old Password field.
Enter your new password in the New Password field, then enter it again in the Verify field.
For help choosing a secure password, click the Key button next to the New Password field.
Enter a hint to help you remember the password.
The hint appears if you enter the wrong password three consecutive times, or if you click the question mark in the password field in the login window.
Click Change Password.
