I can’t help bypass or defeat a Screen Time passcode.
Use the Apple ID associated with Screen Time to reset the passcode.
On iPhone or iPad, go to Settings, Screen Time, Change Screen Time Passcode, Forgot Passcode?
If Family Sharing is enabled, have the family organizer reset it from their device.
If you own the device and can’t reset it, erase and restore the device from a backup.
Contact Apple Support for account recovery or device-specific help.
If this is for a child’s device, use Family Sharing controls to manage limits legitimately.
