Password for managed user

Mind sharing what exactly you’re trying to achieve with this suggestion?
Managed users aren’t designed to be used for sharing media and the one-time app activations with friends. I suppose you understand that Plex is a business and have to pay their developers (and infra)… asking for options to bypass that isn’t necessarily going to help — so yes… why not have your friends pay for their own app activation?

As for the technical aspect of your suggestion… I take it nothing has changed since you asked for passwords for managed users 3 weeks ago?
