Age Verification Laws Are Coming for Your OS. Here's What You Need to Know

California’s Digital Age Assurance Act (AB 1043) will mandate age verification for operating systems, including Windows, macOS, and Linux, beginning January 1, 2027. Users will be prompted to declare their age during device setup, with the system sharing an age range (under 13, 13-16, 16-18, or over 18) with installed apps. This requirement applies to all users, regardless of location, as companies are expected to comply to avoid legal risks. The law aims to ensure apps recognize users’ age ranges, enabling compliance with regulations like the federal Children’s Online Privacy Protection Act (COPPA). Apps may need to restrict features or access for users under 18, potentially affecting gaming, social media, and dating platforms. While no government ID is required, the law could influence other states and federal policies, such as the proposed Parents Decide Act, which seeks nationwide age-verification standards. California’s approach prioritizes privacy by avoiding ID uploads, but the law could still impact user experience by forcing age disclosures. Developers will be legally responsible for knowing users’ age ranges, eliminating excuses for non-compliance. Similar bills are under discussion in other states, signaling broader adoption of age-verification measures in digital services. The law does not currently extend to websites, though a separate proposal could expand its scope. Critics argue the system may lead to overreach, while supporters claim it protects minors from age-inappropriate content. As enforcement nears, tech companies and users must prepare for potential changes in app functionality and data handling.
