Google plans to launch a pioneering age assurance tool in the United States (US), evaluating whether an account is being operated by a minor or an adult.

The Mountain View-based tech giant revealed on Thursday, July 31, 2025, that the feature is designed to be a protection tool for children, and if any minor users are detected, Google will turn on its age-appropriate experiences.

In a blog post, Google detailed its age assurance system, stating that it has several measures in place to protect younger users when they use the company's products.

This sophisticated technology is designed to bolster online safety and protection for young users. It is worth noting that the tech giant will now use its machine learning (ML) tool, Age Assurance, to identify these users and implement these measures in the US.

Instead of looking at the date of birth of the account holder, the model interprets a wide range of signals that are associated with an account. These include the type of information searched by the user or the category of videos watched on YouTube.

If the tech giant estimates a user's age to be younger than 18, it will notify them via email as well as whenever they interact with Google products.

“The notification will inform them that their settings are being changed to include child safety features. This will roll out in the US in the next few weeks to a small subset of users,” Google stated.

Some of these features include enabling YouTube Digital Wellbeing tools, such as reminders to take a break and go to bed, safeguards for content recommendations, and limiting repetitive views of specific content.
