Tap Settings on the home screen then tap on Security.  Tap passcode, then enter the current passcode.  You now have the choice to enter a password or a passcode.  The process is the same for both: Tap Passcode once more, now enter your new passcode and verify by entering it again.  Please email the new passcode/password to itsupport@seacrest.org so IT can access the board if needed when you are away.
