New U.S laws designed to protect minors are pulling millions of adult Americans into mandatory age-verification gates to access online content, leading to backlash from users and criticism from privacy advocates that a free and open internet is at stake. Roughly half of U.S. states have enacted or are advancing laws requiring platforms — including adult content sites, online gaming services, and social media apps — to block underage users, forcing companies to screen everyone who approaches these digital gates.

“There’s a big spectrum,” said Joe Kaufman, global head of privacy at Jumio, one of the largest digital identity-verification and authentication platforms. He explained that the patchwork of state laws vary in technical demands and compliance expectations. “The regulations are moving in many different directions at once,” he said.

Social media company Discord announced plans in February to roll out mandatory age verification globally, which the company said would rely on verification methods designed so facial analysis occurs on a user’s device and submitted data would be deleted immediately. The proposal quickly drew backlash from users concerned about having to submit selfies or government IDs to access certain features, which led Discord to delay the launch until the second half of this year.
