My student has no email address of his/her own. How to invite him/her to join my room?

ClassDo authenticates all sign-ups and sign-ins via a one-time verification code.

Hence all users need to register their account with an email address in order to receive the one-time verification code. Please advise your student to register for an email account.

Can siblings share one user account?

We recommend every user to have his or her own account for security purpose. This also helps to prevent siblings from entering each other's rooms or accessing each other's files by mistake.
