Ps4 share how are you?

How does account sharing work on ps4? E.g. Can I download the games from multiple accounts or can I only share 1 person? If 1 person gives me their account and I download their games, can I log out of their account and share with someone else without losing the games?

You have to activate the primary ps4 on the other acc, you can find that under settings.

If you deactivate primary ps4 on the other then your authorization for your game is gone means you can only share the authorization from one acc at the same time.
