The assignment timer starts when your student clicks the link in Canvas™ to open it, but assignment restrictions such as entering the password might prevent your student from beginning work immediately.
Cause
Timed assignments can be scheduled with additional restrictions, including conditional release, password protection, IP restrictions, or LockDown Browser®. When opened from Canvas, the restrictions are checked after the timer starts instead of before the assignment is opened. This can result in students having less than the allotted time to complete the assignment.
Prevention
Resolution
When this problem happens to a student, grant the student extra time
for the timed assignment in WebAssign.
