<p>
YouTube is testing a new AI-driven age verification system in the U.S., which may restrict mature video access based on behavior, account age, and viewing habits.
</p>
<p>
If the system misclassifies you as under 18—even if your account is decades old—you may be prompted to verify your age using a government ID, credit card, or selfie.
</p>
<p>
This is currently a trial for a small number of users, starting around August 13, 2025.
