After installing the Badgr LTI, Canvas admins, teachers or students are presented with an "Authentication failed" message, as pictured below.
This error most often occurs when installing the Badgr LTI for the first time, but occasionally occurs with users who have been using Badgr for some time.
Incorrect Consumer Key and Shared Secret
If you are new to Badgr and encounter this message, it typically means the Consumer Key and Shared Secret were entered incorrectly when installing the LTI app. The Key and Secret may be incorrect for a variety of reasons. The most common causes are listed below.
- The Consumer Key and Shared Secret were copied incorrectly or incompletely. For more information see: How to find a Consumer Key and Shared Secret
- Your primary Canvas email does not match one of the emails on Your Badgr account. To add an additional email to your Badgr account see: Managing your Badgr Account. Your primary Canvas email can be found when logged into Canvas by selecting "Account," then "Settings." It will be on the right side and will be marked with a star.
- You are connecting to an account on a different server. You may experience this error if your Canvas instance was authorized on a different server than your Badgr account. For example, if your Canvas instance was authorized on the EU server, and you are connecting to a Badgr account on the US server, then you will experience this error. Please be sure that you copy the Key and Secret from your Badgr account on the same server as your Canvas instance.
