Create Classroom for my students

Hi Everyone !
I m a teacher and want my students to create an App using MIT App Inventor. Need help for some classroom group creation as i don't want my students to login using their email account. Please help.

Do you mean Google Classroom ?

If not you can try the Code server, which does not require an email login

follow Tim' recommendations. Realize, at the present time only one student at a time can log into and access the group Project.
