What is the difference between LTI 1.1 and LTI 1.3?

The version of LTI that has been most widely adopted is LTI 1.1, also known as LTI Standard. WirisQuizzes is compatible with LTI 1.1; however, this version has been in the market for over five years. There have been a couple of other versions, such as LTI 1.2 and LTI 2.0, but we don't support either due to security considerations.

Moodle, Canvas, Blackboard, D2L and Sakai are already moving to LTI 1.3, and they will be encouraging other LMSs to upgrade to LTI 1.3 as soon as possible. One of the main reasons is the modernized security model, and the other is the idea of having different services layered on top of a core LTI launch mechanism that will allow a new set of interactions between tools and platforms. LTI 1.3 ensures the most up-to-date privacy and security model.

What's new with LTI 1.3

• Introduction of the IMS Security Framework specification prescribing improved security based on the 0Auth2 and JSON Web Tokens.
• Improved documentation and migration guidance to help move the market from the benefits of basic launch to the full suite of LTI possibilities.
• Alignment with the LTI Advantage set of services that enable a fully integrated and innovative digital ecosystem.
