Forgot iPhone passcode

You can’t get it back. You must restore your phone to factory settings, then restore a recent backup. See this Apple support link→If you forgot the passcode on your iPhone, or your iPhone is disabled - Apple Support

Or watch this companion video ⬇️

If your iPhone has been set up/synced on a computer before, try connecting it to the computer you used to setup/sync the phone. If you have not synced your iPhone before to a Mac or a PC, your only legal option is to restore the device to it’s original state and set your iPhone up from there.
