Hello @XingchenZhang,
I am not sure if you are a Canvas administrator, student, or teacher but I will do my best to help you.
If you are a Canvas administrator, you should:
- go to the Respondus website and use the "Admin Login" link to access the administrator area
- in the administrator area, read through the admin guide
- based on how your institution is is designed, work with your Instructure/Canvas customer success manager and Respondus Support in order to properly integrate the Canvas LMS and Respondus LockDown Browser together
If you are a teacher or student, I would encourage you to contact your Canvas team and ask for help with logging into Canvas from within the Respondus LockDown Browser.
Please come back and let us know how it goes or if you need anything else.
