Your password will probably be written in your physical passport (if you have one).
If you can't find your password, ask the adult the that registered you to sign in to their 'mission control' and find it for you.
If you have forgotten your password, please enter your email address below. An email will be sent to you with further instructions.
If you have forgotten your child's password, sign in to your 'adult mission control' where it will be listed next to your child's name on the right of the screen.
There is a video in the 'Help' section if you're having difficulty locating it.
