I have an account for my own practice/learning using chrome. I want to teach my child on the same computer. I set up a classroom and have a separate username and password for this student. I cannot login using this student identity. On chrome I am sent directly to my own account. Following a helpful comment on another discussion forum I tried signing the student in using another browser, Firefox. On firefox the login details don't seem to work and the message to sign in comes up as blank again. What can I do? My child does not have an email account.
