We watch password-protected videos on Yandex

So you want to look at video.yandex.ru someone's password-protected video. For this, it is necessary that at least 1 video of this user be without a password. We start the non-password-protected video, copy the embed code, paste it onto any page, now start 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 video open for viewing, a password-protected one is also offered. No passwords are required. Click and look.

Example.
