As the teacher, you can edit a student’s account info and character by clicking the pencil button across from their name in the “Students” section of your class settings.
There, you can change their first and last name, their email address, and their username and password. You can also change aspects of their character: their gender, skin tone, and character class. (You can read more on changing their character class here.)
Additionally, you can remove a student from your class by clicking the red "remove" button. (To learn how to move a student to another class group, click here.)
In their accounts, students can add their email address or link their account to Google, Microsoft, Facebook, or Twitter.
