A webcam is necessary to complete verification. If you do not have a webcam, you can certainly use any other computer to verify. We recommend that you ask if your local library has available webcams or borrowing a friend’s webcam.
Photo verification is not available in the mobile app at this time, but you can also verify your identity using a newer smart phone by navigating to https://courses.edx.org/verify_student/reverify in a mobile browser.
Note that you only need the webcam to verify your identity. You do not need the webcam to complete course work.
