Age Assurance Laws: What Developers Need to Know

Age assurance laws are being proposed worldwide to protect children and teens online. These regulations aim to restrict minors' access to certain content or services, often requiring devices, operating systems, or app stores to collect age data and share it with apps. While the intentions are commendable, poorly crafted rules can unintentionally burden open source projects and developer infrastructure that pose minimal risk to young users. Below, we answer key questions developers should consider as these proposals evolve.

What exactly is age assurance?

Age assurance refers to methods used to determine or estimate a user's age. It's often confused with age verification, which involves higher-confidence techniques like photo ID matching or checks against financial systems. Age assurance includes a broader spectrum: self-attestation (users state their age), age estimation (inferred from facial scanning, behavior, or signals), and other approaches. There's ongoing debate about tradeoffs between accuracy, privacy, security, interoperability, and accessibility. Proposals vary widely in which age thresholds trigger restrictions, what content or services are covered, how parental consent is handled, and how access is limited. For developers, understanding these nuances is crucial because the technical implementation choices in a law can have profound effects on how software is built and distributed.

Why should developers care about age assurance laws?

Developers are directly impacted by how age assurance requirements are scoped. Many proposals target “publishers” of operating systems, app stores, or devices—but definitions can be broad enough to include individual open source maintainers. For example, a law that mandates centralized collection and management of user data by operating systems conflicts with the decentralized, user-controlled norms of open source ecosystems. Similarly, restrictions on installing software outside of curated app stores would harm the very nature of open source distribution. Developers who contribute to infrastructure services, tools, or operating systems could face heavy compliance costs, even if their projects don't pose the same risks to minors as consumer-facing platforms. Engaging early in policy discussions helps ensure these laws don't inadvertently stifle innovation and learning opportunities.

What harms do these laws aim to address?

The laws target serious online risks to minors: grooming for sexual purposes, exposure to violent content, and online bullying. These are genuine concerns that deserve thoughtful regulation. However, policymakers must also recognize that online participation—including in open source development—plays a vital role in young people's education and social lives. Learning to code, contributing to projects, and engaging in community discussions can be formative experiences. The challenge is to strike a balance between protection and freedom without inadvertently restricting beneficial activities. Age assurance laws that are too broad or technically prescriptive can block access to legitimate educational resources and collaborative platforms that teens rely on.

How could age assurance laws affect open source projects?

Poorly designed age assurance laws could have significant unintended impacts on open source software. For instance, requirements that operating systems centrally collect and manage user age data would conflict with the decentralized, user-controlled principles of open source. Another risk is placing age assurance obligations on “publishers” of operating systems, which could include individual developers who distribute Linux builds or custom Android ROMs. Such laws might also require that only app stores with age verification features can install software, effectively blocking sideloading and package managers common in open source. These measures not only impose technical burdens but also raise privacy concerns, as centralized age data collection creates a honeypot for attackers. Open source projects often lack the resources to implement complex age assurance systems, potentially pushing them out of the ecosystem entirely.

What can developers do to engage with age assurance proposals?

Developers should actively monitor and participate in policy discussions. Start by reading proposed legislation in your region and submitting feedback through official channels. Highlight how technical details—such as definitions of “publisher,” “operating system,” or “app store”—can inadvertently capture open source projects. Collaborate with organizations like the Open Source Initiative or Electronic Frontier Foundation that advocate for balanced policies. Propose alternatives that achieve safety goals without undermining decentralized development, such as client-side age estimation that preserves user privacy. Also, educate policymakers about the specific way open source operates: volunteers maintaining code, distributed contribution models, and the importance of software freedom. Early engagement can shape laws to protect children without crushing the collaborative internet that fosters innovation and learning.

Do age thresholds vary across proposals?

Yes, considerably. Some laws set the threshold at 13 (in line with COPPA in the US), others at 16 or 18 (as in the UK's Age Appropriate Design Code). The age at which restrictions kick in changes what content or services require age assurance. For example, a threshold of 13 might allow teens to access educational resources without friction, while 18 would require age checks for almost all content. The choice of threshold also affects how age assurance is implemented—younger children might need more robust verification, whereas older teens could rely on lighter methods like self-attestation. Developers building applications that cater to mixed-age audiences must design flexible systems that can adapt to different jurisdictional requirements. A one-size-fits-all approach rarely works, making it essential to track multiple regulatory frameworks.
