Yes!

If your child already has their own Google Account, you can add supervision and manage their parental controls with Family Link.

If your child under 13 (or the applicable age in your country) doesn't have a Google Account yet, you can create one for them and manage it with Family Link.

If you add parental supervision to your child's existing Google Account and your child is above the applicable age in your country, you or your child can stop supervision at any time. If your child stops supervision, you'll be notified and your child's supervised devices will be locked temporarily.

Important: Stopping supervision may work differently for children under 18 who live in Japan and are using a Pixel phone.

Requirements

To add supervision to your child's existing Google Account, you need to:

Have a Google Account yourself. If you don't have one you can create a Google Account at no charge.

Recommended: Have an Android device (5+), iPhone or iPad (iOS 13+), or Chromebook (M69+) to download the Family Link app on.

To let a parent supervise their existing Google Account, a child needs to:

Agree to parental supervision.
Live in the same country as their parent.
