Determine when a Student Last Logged into Canvas
You can determine when a student last logged in to your Canvas course by clicking People in your course navigation.

The Last Activity column displays the date and time of a user’s most recent interaction in the course. This time stamp updates when a user navigates through the course using the Course Navigation menu, replies to a discussion or submits an assignment or quiz, and when they access course files and pages.
Please note that Last Activity does NOT include mobile interactions on the Canvas app or group participation, so it may not be a fully accurate representation of a student’s participation in Canvas.
