This may happen if, for example, you are the coordinating teacher for THE BIG CHALLENGE at your school and only received access to your account through a so-called magic link. The account was generated automatically to edit your participation. You can find the MagicLink in the confirmation e-mail which was sent to you right after your registration for the competition. Using the MagicLink you can create a password in your account details on the upper-right-handside to gain access to your account without having to use the Magic Link.
If you no longer have the confirmation e-mail please contact us.
Otherwise, if you know which e-mail address you used, you can use the "Forgot password" button or simply contact us if you have any further questions:
