How do I update the passcode on a Family Watch after initial setup?

Hi there vesu0073,

Welcome to Apple Support Communities. The passcode on your daughter's Apple Watch can be reset from the iPhone used to set it. In this case, you can reset her passcode for her from your device. Follow these steps to do so:

Manage a family member's Apple Watch after you set it up

You can use your iPhone to adjust settings and customize features on a Family Setup watch:

1.Open the Apple Watch app on the iPhone that you used to set up the watch.

2.Tap All Watches, tap the watch under Family Watches, then tap Done.

3.Choose a setting to adjust.

Complete details can be found here: Set up Apple Watch for a family member

Let us know if you have any questions.

Best regards!

Hi vesu0073,

If the above steps did not help and you're still unable to change the code, we'd recommend reaching out to Apple directly to look into this with you further. You can reach out to them and get started by going here: Get Support

We hope that helps you out.

Take care.
