Set the child’s account before the screen time limit

Most screen time limits fail because they were set on a login the child can control.

What you need

Allow roughly fifteen to twenty minutes for each computer. The exact time depends on updates, account passwords, and whether the child already has a login.

Gather your administrator credentials before you start. You’ll also need an email address for a Windows child account and a passcode for macOS.

• Your administrator login on each computer
• An email address for the child’s Microsoft account
• Your Microsoft account credentials
• Admin access on the Mac
• A new macOS user account for the child
• A Screen Time passcode the child cannot guess
• A short test session after setup

A shared login cannot hold a per-person limit

A computer sees the active account, not the person sitting at the keyboard. One shared login therefore cannot apply a separate schedule to each family member.

The same limit affects everyone, or anyone using the login can change it. A child with administrator access can also alter settings or create another route around the rule. Before you commit to anything, it is worth looking at set limits on kids laptop.

Create a separate account and keep your administrator credentials private. Paid software becomes useful when you manage several computers, need reports, or want extra filtering.

How to set screen time limits on a computer with Windows

Windows Family Safety needs a Microsoft account connected to your family group. The child’s Windows profile also needs to be a Standard User, not an Administrator.

A local Windows account does not receive Family Safety time limits. Check the account role before you create the schedule. People in this spot often ask about setting up parental controls on phone as well.

1. Create or add the child’s Microsoft account at account.microsoft.com/family. Accept the family invitation if Microsoft sends one.
2. On the computer, sign in with the child’s account. Add it through Settings > Accounts > Email & accounts if Windows has not added it yet.
3. Check the role in the account settings. Use the tip below if the account is still an Administrator.
4. Open family.microsoft.com, select the child, and choose Screen time. Add the computer, then set daily hours and allowed periods.
5. Sign out and let the child sign in. Check whether Windows shows the schedule and the remaining time.
6. Test the rule with a short allowed period. At lockout, Windows shows a message saying time is up and offers a Request more time option when the family organiser allows requests. The parent approves extra time from Family Safety, and the child can continue only after approval.

The macOS steps and the Screen Time passcode lock

Create the child’s account while signed in as an administrator. Screen Time then applies to the child’s Mac login.

If the child is in your Family Sharing group, set the passcode and limits from your own account remotely. Otherwise, sign into the child’s session and set the passcode there.

1. Open System Settings > Users & Groups on your administrator account. Add a user for the child and leave the account as Standard.
2. Open System Settings > Family on your Mac, select the child, and choose Screen Time if Family Sharing manages the account. If remote controls are unavailable, sign into the child’s account instead.
3. Set Downtime for blocked hours, App Limits for daily caps, and Always Allowed for approved apps.
4. Set a Screen Time passcode that the child has never seen. Don’t reuse the Mac login password.
5. Test the rule with a short limit. macOS shows a time-limit screen and prevents the restricted app or service from opening until time is granted or the schedule changes.

Guest access and other gaps need a separate check

Guest access can bypass a child account because the guest session has its own settings. Disable it before testing the limit.

Windows Home has no Guest account to remove. On Pro, disable it in Computer Management > Local Users and Groups, or simply leave no other usable accounts on the machine.

On macOS, open System Settings > Users & Groups > Guest User. Turn off Allow guests to log in to this computer. Older macOS versions use the same Guest User switch in System Preferences.

Windows Family Safety and macOS Screen Time apply only to configured accounts and devices. A second computer needs its own setup, and a school laptop remains outside your control.

Clock changes can affect scheduled hours on some systems. Keep automatic date and time enabled, then test the boundary yourself. Open a restricted app just before the limit ends and again afterward.

Chromebooks use Google Family Link

Chromebooks are outside the Windows and macOS steps above. Google Family Link manages supervised child accounts, while ChromeOS applies the account’s device rules.

Install Google Family Link on your phone, create or supervise the child’s Google account, and add the Chromebook under the child’s devices. Use Family Link’s screen-time controls to set daily limits and bedtime.

The child sees a warning as the allowed time approaches. At the limit, the Chromebook locks or blocks access until the schedule allows use or a parent adds time.

Menu names can change between ChromeOS releases. Open the Chromebook’s Settings and search for Family Link or parental controls if the device does not appear in the app.

Linux and paid tools serve different needs

Linux has no direct built-in equivalent to Family Safety or Screen Time. A router schedule can pause internet access for a device during chosen hours.

That schedule limits connectivity, not computer use. Offline games and downloaded videos still work, so test the rule against the activities you want to restrict.

Parents managing several computers may prefer central software. A tool like SentryPC offers central scheduling and per-user limits across several machines. It may also include filtering and activity reports, depending on the plan and platform.

Check the current product page before buying. Features can differ by operating system, subscription, and account type. A single computer with one simple schedule may not need paid software.

A cloud dashboard can reduce repeated setup across machines. It cannot control a phone or tablet unless the product supports that device and you configure it separately.

Common mistakes

These problems usually appear during the first test. Fix them before relying on the schedule during homework or bedtime.

• Leaving Windows set to Administrator -> Change the account to Standard User before scheduling
• Using a local Windows account -> Add the child through a Microsoft family account instead
• Skipping the macOS passcode -> Set it through Family Sharing or the child’s session and keep it private
• Forgetting another computer -> Configure every machine the child can use
• Testing only the schedule page -> Let the child reach the limit and check the lockout screen
• Leaving automatic time settings off -> Enable automatic date and time before testing

Questions people still ask

I have watched parents spend an evening on schedules that failed the next day because the child’s account remained an Administrator. Check the account role, then test the lockout screen.
