Private by default
Your videos. One link each. Nothing public.
Upload a video, hand out a single link, and lock it with a password whenever the audience matters.
One link per video
Every upload gets its own unguessable address. Nothing is ever listed publicly.
Password when you want it
Add or remove a password on any video at any time, without changing the link.
Everything in one list
Your dashboard shows every video, its link, its password state and its size.
