iPad app for video playback of password protected site with speed control

I’m looking for an iPad app that will play back video from a retreat I attended that is password protected, that also allows playback at 1.x speed. I use Vimeo Repeat and Speed on Chrome on the Mac to do this, but have been unable to find a way to do this on my iPad… any help most appreciated!

Maybe this shortcut (from the MacStories Shortcuts Archive) might work?

Have you tried VLC?

You can change the speed of playback
and enter a password if I understand
what you are looking for

Thanks, but sadly none of these options work on a password protected site (at least not the one from this retreat). VLC is great, but cannot get to the site…
