Students do not have to register to use Classtime. They only need a device and the Session code.
With the Session Code, a student can join a live Session by providing his or her name or nickname, which will then be valid for this one Session only.
However, students can authenticate with their Google, Microsoft, or Clever accounts. The authentication is only used for identifying the student in your Sessions. We will never contact your students.
Pro tip: joining with Google, Microsoft, or Clever accounts instead of nicknames has several advantages advantages:
Student names are accurate and consistent
Better guarantee of real student identity
Progress saving: students can log into the same Session at another time and from another device and continue where they left off!
