To reset or change your iPad's passcode, you can use the "Passcode" menu in your Settings app, or reset the entire device.

Losing access to your iPhone’s Screen Time passcode can be a significant inconvenience, especially when it limits your ability to manage app usage, content restrictions, or device settings.

You can remove your password from an iPad in a few steps through its Settings app, and it's easily reversible if you ever want to add one again.
