Age Verification Laws Are Quietly Becoming Mandatory Identity Checks Online

A wave of under-16 social media bans — led by Australia’s December 2025 law and now being copied across the UK, EU, France, Spain, and several other countries — is forcing platforms to verify users’ ages through biometrics, government IDs, or third-party apps. The mechanics matter: to avoid heavy fines, companies must keep under-16s logged out, which in practice means collecting sensitive identity data or profiling users based on data they already hold. Services like Snapchat already route verification through foreign firms (k-ID in Singapore), raising unanswered questions about data retention, breach exposure, and susceptibility to government demands in jurisdictions users know nothing about.

The early evidence suggests the tradeoff buys little. Australia’s own research found roughly 70% of kids still used social media months after the ban, and a British Medical Journal study found no substantive drop in adolescent usage. Meanwhile the privacy costs are concrete rather than hypothetical: weeks before the ban took effect, a breach of a third-party support app Discord used for age-assurance complaints exposed government ID images, names, emails, and billing data for nearly 70,000 Australians. Regulators also documented providers over-collecting and over-retaining data in anticipation of future investigations, amplifying breach risk at scale.

The deeper shift is structural. As the Australian Human Rights Commission frames it, the law effectively requires people to be profiled in order to participate online — and even users who pass an age check may self-censor once anonymity is gone. The UK is promising an “Australia-plus” regime with stricter enforcement, signaling that the harder governments push to make these bans bypass-proof, the more identity data they compel platforms to collect. The piece’s core argument: these measures are unlikely to make the internet meaningfully safer for children, but they will make it markedly less private and less free for everyone.
