Full screen video from a link - can anyone advise?

Any kind souls out there who can point me in the right direction? I’m working with a video editor to create a marketing video for a business idea. I hope to email a link (and ideally a password) to potential customers, have them click on the link/enter PW and have it display full-screen video on their screens, ideally regardless of platform. Also with a small player along the bottom so it can be viewed again. Can someone help a clueless non-dev guy out and point me in the right direction? I can’t find info on how this is done and who I’d need to hire but assume it must be a common need. Is there an affordable solutions provider who offers this? I paid for an inexpensive Vimeo subscription, but turns out Vimeo isn’t the solution. Do I need someone via UpWork or similar to set it up on AWS? Any advice or direction is appreciated! Thank you.

Hello, you can use password to see video on vimeo.
