Do I need an account to use Cornerstone Classroom?
You don't need a Cornerstone Classroom account if you are joining Cornerstone Classroom as a participant. That is, if someone invites you to their meeting, you can join as a participant while the attend process creates a guest account for you. However, if the host has restricted joining meetings using authentication profiles, then you need a Cornerstone Classroom account to access the meeting. That is, you can attend the meeting only after providing the username and password of the registered account.
A Cornerstone Classroom account is required if you need to create your own meetings and send invitations to participants. A Cornerstone Classroom account allows you to create your own instant meetings or schedule meetings. An account also allows you to access your personal settings, where you can update your profile at any time.
