Multiple Users for one account

[OnlymyPlays]

Hello !
I'm was wondering if there was an easy way to have multiple users for one account.
The main idea between this concept is to have a system like Netflix has. For instance, be able to switch easily in a menu between accounts.

I've read the documentation but found nothing relevant to solve this problem.

Anyone has a potential idea to solve this ?

I wish you a nice day !
