Google’s system doesn’t require an ID or selfie verification—it’s connected to the company’s existing Family Link app. The idea is that parents will set age ranges for their kids’ managed accounts. For example, you might set a range like 16–17, allowing apps to tailor experiences and content for teenagers. Google notes that the ranges are dynamic and may change as young users get older. So a kid who’s 13 may be in the same app content bracket for a few years before hitting the next level. Parents have the option to set and share these ranges if they want that additional level of control over what their children can access in Google Play. However, it’s not mandatory for child accounts—it’s fully opt-in and can be turned off at any time.
