Meta will have to introduce time limits, nighttime restrictions, and changes to the algorithms and age-verification systems on Facebook and Instagram for users under 18 in the United States. Among the measures is a default cap of two hours a day across both platforms combined, a result of the agreement the tech company reached to resolve lawsuits filed by numerous US states.
Meta’s new restrictions in 30 seconds
- Teens will have a default cap of two hours a day combined across Facebook and Instagram, though there are exceptions and parents will be able to modify certain restrictions.
- Meta will introduce pauses, usage alerts, and nighttime and school-hours limitations.
- Minors will be able to access a chronological feed without personalized recommendations.
- The company will have to strengthen its age-estimation systems to prevent a false birth date from bypassing the protections.
The change is especially significant from a technological standpoint because it affects some of the core mechanisms that power today’s social networks: algorithmic recommendations, continuous content playback, notifications, engagement metrics, and personalization.
The agreement reached with the states also includes payments that could exceed $17 billion over the coming years. Meta has not admitted wrongdoing, but it has agreed to change the experience Facebook and Instagram offer to minors.
Two Hours for Facebook and Instagram, and Limits on Continuous Scrolling
The most visible measure will be the default cap of two hours of combined daily use.
This isn’t two hours on Instagram and another two on Facebook, then. Time used across both platforms will accumulate toward the set maximum.
Messaging will have exceptions, and parents or guardians will be able to modify certain restrictions. This means the system works more as a restrictive default setting than as an absolute block imposed on all teens.
Meta will also have to intervene on prolonged sessions.
The platforms will show alerts after continuous browsing periods and will introduce pauses once accumulated usage reaches certain thresholds. The goal is to reduce so-called doomscrolling, the continuous scrolling through feeds that can serve up content with virtually no limit.
This is where an essential feature of modern social network design comes into play.
Users no longer need to decide what they want to watch next. Recommendation systems automatically select another post, video, or Reel based on signals such as viewing history, interactions, or the behavior of users with similar profiles.
Removing natural stopping points makes much longer sessions easier.
The new rules attempt to artificially introduce some of those stopping points.
There will also be restrictions overnight. Between midnight and 6 a.m., access to different features will be limited, while notifications will be turned off by default during certain nighttime and school hours.
The measure doesn’t mean teens will disappear from Facebook and Instagram at night. Messaging retains exceptions and parental oversight mechanisms exist, but it does change the default setup accounts will run under.
Meta Will Have to Offer an Alternative to the Personalized Algorithm
Another change directly affects the recommendation system.
Teens will be able to use a feed without personalized recommendations, based mainly on the accounts they follow and organized chronologically.
The difference matters.
The algorithmic feed tries to predict what content will maximize each user’s interest. To do so, it draws on numerous signals from their activity and from patterns detected among other users.
The chronological feed reduces that intervention and shifts more weight back to an explicit decision: the accounts the user has chosen to follow.
But Meta will not remove the personalized algorithm from teen accounts.
The alternative will be available, and parents will be able to set it as the default through supervision tools, but recommendations will remain part of the platforms.
It will also be possible to limit features such as autoplay.
The agreement also affects another signal that has historically defined social media: “likes.”
Facebook and Instagram will hide certain engagement counters by default for teen accounts. The intent is to reduce constant exposure to public metrics that quantify the response a post receives.
Meta will also have to apply additional restrictions on certain filters that alter physical appearance, including certain cosmetic effects.
Age Verification Becomes the Central Technical Problem
There’s an obvious difficulty behind all these measures.
Facebook and Instagram need to actually know a user is a minor.
A system based solely on asking for a birth date would be relatively easy to get around. Simply entering a different age when creating the account would suffice.
Meta will therefore have to strengthen its age-estimation and verification technologies.
The company has long been developing systems capable of inferring whether an account likely belongs to a teenager using various signals. The agreement raises the stakes for those technologies, since much of the new restrictions will depend directly on how well they work.
This creates a difficult balance between three goals: protecting minors, preventing them from getting around the restrictions, and not unnecessarily requiring ID documents from every user.
The problem isn’t unique to Meta.
YouTube, TikTok, Snapchat, and other major platforms face a similar issue as governments and regulators introduce different rules for adults and minors.
If legislation requires offering different experiences depending on age, determining age stops being just a profile field and becomes part of the service’s access infrastructure.
Artificial intelligence will likely play an increasing role in that process, through models capable of estimating age ranges from various signals. But those systems also introduce potential errors: an adult could be classified as a minor, and a teen could manage to be identified as an adult.
How effective the new measures are will largely depend on that margin of error.
Social Media Design Enters a New Regulatory Era
The US agreement has another technological consequence that goes beyond the number of hours allowed.
For years, platforms have competed to boost metrics such as usage time, sessions, views, and engagement. Much of their recommendation and design systems have been built around those goals.
The new restrictions introduce a different logic for minors.
A platform can keep trying to show relevant content, but certain mechanisms designed to indefinitely extend a session will now face additional limits.
That doesn’t mean recommendation algorithms will disappear, or that Instagram will stop using artificial intelligence to select content.
It means product design will have to incorporate restrictions that, until now, relied mainly on voluntary digital-wellbeing tools or parental controls.
The change could also have consequences for how future features are developed.
A new feature designed to boost engagement will now have to be evaluated not just for its ability to increase usage, but also for how it fits within the protections that apply to minors’ accounts.
And there’s an important caveat: for now, we’re talking about the United States.
The agreement doesn’t automatically set a two-hour limit for European teens, nor does it require applying exactly the same settings in Spain. Meta also operates under different regulatory frameworks depending on the country.
What the agreement does show is where the tech debate is heading.
Protecting minors is no longer limited to parental controls layered on top of an app designed the same way for everyone. It increasingly affects the code itself, the algorithms, the interfaces, and the architecture platforms are built with.
Frequently Asked Questions
How much will minors be able to use Facebook and Instagram in the United States?
The default cap will be two hours a day combined across both platforms. There will be exceptions for certain features, and parents will be able to modify some restrictions.
Will Meta remove recommendation algorithms for teens?
No. Minors will be able to use a feed without personalized recommendations, and parents will be able to set it as the default, but the algorithmic recommendation systems won’t disappear entirely.
How will Meta know if an account belongs to a minor?
The company will have to strengthen its age-verification and estimation mechanisms to detect teen accounts even when a different birth date was entered.
Will the two-hour limit also apply in Spain?
Not as a result of this agreement. The measures apply to the United States and don’t automatically set the same limit for Spanish users. As France’s own attempt to verify minors’ age on social media has shown, European regulators are still working out how to enforce similar protections without overreaching into everyone’s privacy.
