Help a non-techy person out, please!

[feejee]

Wasnt quite sure where to put this, so Chat it is. I am sure someone here will be able to help me. Its a techy question to help me with work.

I have video recordings of workshops that ran, and i want to only share with certain people outside of my organisation, how could i do this? We have a youtube channel but ive only ever used it for publicly available videos. I now need to make these new ones only available to paid delegates. Is there another platform i could use that would give us password protection option?

Whilst im at it, could anyone advise on where you would upload podcasts? Free to all. (I feel like a dinosaur not knowing about this stuff).
