Educators must enter student names (partial names or pseudo names work) and must not include student email addresses. The app will automatically generate a unique username and password for each student. The educator then provides this information to each student.

By using this method while setting up student accounts:

• The app's social interaction options are disabled and not impacted by the class privacy settings

• Student age is not requested, and students are unable to share their personal profile information on the web

• Students are unable to login or access any social media accounts through the app

• In-app purchases are disabled automatically

• Profile pictures and bio features are not available to students.

For additional help, Please follow "Option #2, signing up your students without student emails"
