VoiceThread supports user authentication using Central Authorization Service (CAS) protocols to allow single-sign-on access. Integration is included in the K-12 District and Higher Education Site licenses, and it can be purchased as an upgrade for other license types. Contact us with any questions or to discuss upgrading.

How to use

  • Email address
  • First name
  • Last Name
  • Role (student, teacher, faculty, staff, etc.)
