What Are Parental Controls?

How parental controls work

Parental controls sit between your child and a device, an account or an app, and they do two things: they decide what gets through, and they lock that decision behind something only you have. The lock is usually a passcode, a PIN or your own account. On an iPhone or iPad, changing most of the settings asks for the Screen Time passcode.^{[3]Apple Support. “Set up parental controls to manage your child's iPhone or iPad”.} On Google Play, a content restriction creates a PIN that has to be entered to remove or change it, and for a child whose account is supervised in Family Link, a parent has to enter their own Google Account password.^{[5]Google Play Help. “How to set up content restrictions on Google Play”.} On YouTube, the content setting of a supervised account can only be adjusted by the linked parent accounts.^{[4]YouTube Help. “Understand your choices as a family”.}

What gets decided varies by tool, but the FTC's consumer advice sums up the common set: most parental controls help you manage how much time your child spends online, restrict the type of content they can access, see their website and app activity, limit who they can communicate with and restrict purchases.^{[1]Federal Trade Commission, Consumer Advice. “How To Use Parental Controls To Keep Your Kid Safer Online”.} The free ones come from the companies that make the devices. Google's Family Link covers Android devices and Chromebooks, Apple's Family Sharing covers iPhone and iPad, and Microsoft Family Safety covers Windows and Xbox.^{[1]Federal Trade Commission, Consumer Advice. “How To Use Parental Controls To Keep Your Kid Safer Online”.}

The part parents find out late is where a control stops. A control belongs to one layer, the device, the account or the app, and it does not reach the others. Family Link cannot supervise an iPhone, an iPad or a computer that is not a Chromebook.^{[2]Google For Families Help. “Set up parental controls for your child”.} A Google Play content restriction applies only to the Android device you added it on, and restricted apps can still turn up in search results or through a direct link.^{[5]Google Play Help. “How to set up content restrictions on Google Play”.} Apps your child downloaded before you set the restriction stay on the device unless you block them separately.^{[2]Google For Families Help. “Set up parental controls for your child”.} This is why the FTC says that to work best, parental controls need to be set up on all the devices your child uses.^{[1]Federal Trade Commission, Consumer Advice. “How To Use Parental Controls To Keep Your Kid Safer Online”.}

Types of parental controls

Most tools offer the same five kinds of control, under different names. The table shows where each lives in the free tools from Google, Apple and YouTube.

The Google column follows Google's Family Link help page, the Apple column Apple's Screen Time page and the YouTube column YouTube's overview for families.^{[2]Google For Families Help. “Set up parental controls for your child”.[3]Apple Support. “Set up parental controls to manage your child's iPhone or iPad”.[4]YouTube Help. “Understand your choices as a family”.}

Two kinds are missing from that table because they are rarer and worth knowing. A website allowlist exists in both Family Link and Screen Time, where Ask to Browse lets you approve sites ahead of time.^{[3]Apple Support. “Set up parental controls to manage your child's iPhone or iPad”.} And a video allowlist, where your child sees only channels a parent chose, exists on YouTube only inside YouTube Kids, where you can handpick specific videos and channels instead of letting YouTube filter.^{[4]YouTube Help. “Understand your choices as a family”.}

What the research says

Parental controls are the technical half of what researchers call parental mediation, next to rules, talking and watching together. A meta-analysis of 57 studies on media time, aggression, substance use and sexual behaviour found that restrictive mediation, which includes rules and limits, had a small but significant relationship with child outcomes, while active mediation was not significant overall but was linked to lower aggression, sexual behaviour and substance use.^{[7]Collier, Coyne, Rasmussen, Hawkins, Padilla-Walker, Erickson and Memmott-Elison, American Psychological Association. “Does parental mediation of media influence child outcomes? A meta-analysis on media time, aggression, substance use, and sexual behavior (Developmental Psychology 52, no. 5)”.} The authors concluded that parents may be able to reduce some negative effects of media with certain strategies.^{[7]Collier, Coyne, Rasmussen, Hawkins, Padilla-Walker, Erickson and Memmott-Elison, American Psychological Association. “Does parental mediation of media influence child outcomes? A meta-analysis on media time, aggression, substance use, and sexual behavior (Developmental Psychology 52, no. 5)”.} In plain words: limits help a little, conversations help with specific things, and no single tool carries the load.

The American Academy of Pediatrics draws the same conclusion for children aged 5 to 18. Its policy statement says the evidence does not support a one-size-fits-all approach and recommends a Family Media Use Plan with consistent rules about media use, boundaries for accessing content and open family communication about media.^{[6]American Academy of Pediatrics, Council on Communications and Media. “Media Use in School-Aged Children and Adolescents (Pediatrics 138, no. 5, e20162592)”.} A parental control is how you make a rule in that plan hold at 7 in the evening when you are cooking.

Example of parental controls

A family with an 8-year-old and an Android tablet sets up Family Link on a Sunday afternoon. The daily limit is 1 hour on school days and 2 hours at the weekend, the bedtime lock is 7:30 pm, apps need a parent's approval to install, and the Google Play maturity level is set for young children. On YouTube they have two choices for this age. The first is YouTube Kids on the Younger setting, with autoplay off and search off. The second is a separate allowlist player such as Pepelly, where the parents pick 10 channels and the tablet shows nothing else; videos play in YouTube's own player, so the app does not remove YouTube ads.

On a Tuesday evening at 6, the tablet unlocks after homework. Family Link counts the hour, the Play Store refuses a game above the rating, and the video app shows only what was approved. At 7:30 pm the device locks itself. What the parents did not get is cover for the family laptop, the TV in the living room or a cousin's phone: each of those needs its own control. The FTC's one-line rule, controls on every device, is the part of the setup that takes the most time.

The thing people get wrong about parental controls. Parents switch on a control and stop looking. The control works, but it only guards the layer it lives on. A supervised YouTube account filters beautifully until your child opens YouTube signed out in a browser on the same tablet; a Play Store rating stops new games but not the three already installed; a Screen Time limit on one iPad does nothing on the Android phone that stayed in a drawer. The setup I would do first is boring: list every screen in the house that your child can hold, and put a control or a passcode on each one, before tuning a single filter. A short list of channels on the one device your child actually uses beats a perfect filter on the device they borrowed.

Parental controls vs an allowlist

An allowlist is one kind of parental control, not an alternative to the whole set. The difference is in the default and in what the parent has to decide.

Most families use both: device controls for time, purchases and the apps that may open at all, and an allowlist inside the one app where the content matters most. How to switch each YouTube control on, step by step, is in the YouTube parental controls guide. If the time side is what you are after, the guide on screen time rules for kids covers the limits by age.

The bottom line

Parental controls are the settings that let you decide, in advance and behind a passcode, what a device, an account or an app will let your child see, do, buy and spend time on. They come free with every phone, tablet and console, and they work on the layer where you set them and nowhere else. Set them on every screen your child can reach, lower the gaps you care about most, and keep the rules at home in plain words, because the controls enforce a plan rather than replace one.
