How do I recover my screen time passcode

How you reset a Screen Time passcode depends upon the system version you are using:

If you or a member of your Family Sharing group have a mobile device running iOS or iPad OS 13.4 or later, or a Mac running Catalina 10.15.4 or later, read this support article for instructions on what to do "If you forgot your Screen Time passcode".

If you still have issues resetting your Screen Time passcode, contact Apple Support.

OR

If you are running a system prior to iOS 13.4, read this Apple Support document about what to do "If you forgot the passcode on your iPhone, or your iPhone is disabled".
