change screen time passcode

Hello arianna165,

Thanks for advising me there's nothing else on this screen. I didn't mean to offend you by providing any of the previous troubleshooting steps. If this is a Family Sharing account, you can reset the password on your own device by navigating to Settings > Screen Time > [your child's name]. Then tap Change Screen Time Passcode 

Make sure you are using your device, not your son's iPhone.

I hope this works and thanks for using the Apple Support Communities!

Hello arianna165,

Welcome to Apple Support Communities! I understand you want to change your son's screen time passcode since he figured it out. I'm happy to assist. To change the passcode on your son's phone, tap Settings > Screen Time > [your child's name]. Then tap Change Screen Time Passcode and authenticate the change with Face ID, Touch ID, or his device passcode. If you forgot the Screen Time passcode, you need to Restore your iPhone, iPad, or iPod to factory settings to remove the Screen Time passcode. Restoring the phone from a backup won't remove the Screen Time passcode.

You can read more about this in the article below:

Use Screen Time on your iPhone, iPad, or iPod touch

Best Regards.

Hi again arianna165,

Thanks for the screenshot. If you scroll down on this screen, do you have an option to turn screen time off? If so, try turning screen time off and setting it back up with a new passcode. If this does not work, you will need to restore the phone using the article I previously provided.

Cheers!
