Introduction

Policymakers worldwide are rapidly advancing age assurance proposals aimed at protecting children and teenagers online. Some measures restrict minors' access to specific services or content, while others require devices, operating systems, or app stores to collect age information and transmit signals to apps and websites. Although these proposals are driven by legitimate concerns, without careful scoping they risk imposing onerous requirements on open source software and developer infrastructure—areas that do not pose the same risks to minors as consumer-focused platforms. This article provides an overview of what developers should know about these laws and how to engage effectively.

The Serious Harms Driving Age Assurance Laws

The issues these laws seek to address are severe and warrant attention. Grooming for sexual purposes, exposure to violent content, and online bullying represent just a few of the dangers young people face in digital spaces. At the same time, participation in online communities—including open source software development—can be a vital part of a young person’s education and social life. Policymakers balancing freedom and protection may not always understand how their proposals could affect developers or how the open source ecosystem operates.

Defining Age Assurance and Age Verification

Age assurance encompasses various methods used to determine or estimate a user’s age. It is sometimes used interchangeably with “age verification,” which typically refers to higher-confidence approaches like photo ID matching or checks against financial or identity systems. Age assurance also includes self-attestation (where users report their age) and age estimation (where age is inferred from signals, facial scanning, or behavior). These methods fall on a spectrum, with ongoing debate about tradeoffs between accuracy, privacy, security, interoperability, and accessibility. Proposals also differ in the age thresholds that trigger restrictions, the services or content covered, the role of parental consent, and how access is limited. While we do not detail every approach here, we encourage readers to engage with legislation, consider technical and policy perspectives, and think about protecting young people online while preserving access to knowledge, learning opportunities, and creative potential—including chances to learn coding and participate in the global open source ecosystem.

Potential Unintended Consequences for Open Source

A poorly designed age assurance law could have significant unintended impacts on open source projects. For example, requirements that operating systems centrally collect and manage user data, or that restrict users from installing software outside of centralized app stores, would conflict with the decentralized, user-controlled norms of the open source ecosystem. Another concern is placing age assurance responsibilities on “publishers” of operating systems, regardless of whether they are individual developers or small groups. Such mandates could stifle innovation, burden volunteer maintainers, and reduce the diversity of software available to users.

The Case of Publisher Requirements

When laws target “publishers” without clear exemptions for non-commercial or community-driven projects, they risk requiring even a single developer who releases an operating system to implement costly age assurance mechanisms. This could deter young developers from contributing, limit educational opportunities, and harm the collaborative spirit that defines open source.

How Developers Can Engage

Developers should actively participate in policy discussions to ensure age assurance laws are scoped appropriately. This includes submitting comments on proposed regulations, joining industry coalitions, and educating policymakers about the unique characteristics of open source development. By advocating for balanced approaches that protect minors without undermining decentralized infrastructure, developers can help shape rules that preserve the internet’s openness while addressing genuine risks.

Conclusion

Age assurance laws are important for protecting young people online, but they must be crafted with care to avoid harming the open source ecosystem. Developers who understand the nuances of these proposals and engage in the policymaking process can help achieve outcomes that safeguard minors while fostering innovation and participation. The goal should not be to restrict access for all, but to target protections where they are needed most without sacrificing the collaborative potential of the digital world.
