Please note that the QR codes are only for elementary classes where the student has iPads in the class they can scan the code and pick their profile and add to their portfolio. There are no passwords required. Whereas for the high school/ middle school mode you need to enter the names of the student and each student will be given a student-specific code using which the student can create an account with email and password. The student will have their own account and they can communicate with the teacher and add to their portfolios and view behavior, calendars, and posts made by the teacher. Currently, the student can only sign up using email, phone number sign up will be enabled very soon. Thank you!
