Use a Screen Time passcode
Set a passcode so that only you can change Screen Time settings and allow more time when app limits expire. If you're a parent, use this feature to set up enforceable content, communication, and privacy limits for your child.
If you're using Family Sharing to manage a child account, follow these steps:*
- Choose Apple menu > System Preferences, then click Screen Time.
- Choose your child's name from the menu in the upper-left corner.
- Click Options in the lower-left corner.
- Select “Use Screen Time Passcode,” then enter a passcode when prompted.
- If you're using the latest macOS, you're offered the option to enter your Apple ID to enable Screen Time passcode recovery, in case you forget your Screen Time passcode.
If you're not using Family Sharing to manage a child account, follow these steps:
- Make sure that you're on the same Mac used by the child, and are logged in to the standard account used by the child. If you're not sure what to do, just continue with the steps below: Screen Time will help you.
- Choose Apple menu > System Preferences, then click Screen Time.
- Set up Downtime, App Limits, Communication Limits, and Content & Privacy with all of the limits that you want for your child.
- Click Options in the lower-left corner.

If you're setting a passcode while logged in to your administrator account, an alert explains that you should do this from a standard account. If you haven't set up a standard account for your child, you can either do that and log into their account, or choose from these options:
- Allow this user to administer this computer. If you choose this option, the passcode affects the current user, even though they're also an administrator of this Mac. This isn't recommended, because administrators have macOS privileges that could allow them to work around passcode restrictions.
- Don't allow this user to administer this computer. If you choose this option, you're prompted to enter your account password in order to modify your configuration. You're then guided through the steps to create a new administrator account—for use by the parent. The administrator account you're currently logged in to is converted to a standard account—for use by the child.
