Launch a non-password-protected video, copy the insertion code, paste it onto any page, now launch the video and wait for the end. As soon as the video reaches the final, Yandex offers a list of videos of this user. And voila! Along with the open for viewing the video is proposed and password-protected. No passwords are required. We press and look.
