Can I share one PlayStation+ account between two PS4's?

I just bought a second PS4. I have one in the living room and one in my game room. My son uses the one in the game room. I only have 1 PlayStation Plus account. If I make the new PlayStation my primary PlayStation, how can my son use the one in the game room to play all the free PlayStation plus games?

Solution 1:

According to the PlayStation FAQ:

You can only activate one PS4™ as your ‘Primary PS4’.

Your primary PS4 has unrestricted access to all content on all accounts. But a non-primary PS4 can only access the content while logged in.

Here's what you can do: set up your son's PS4 as your primary PS4. That way, he will be able to use the Plus features while logged on his account. The downside is that on your PS4, you have to log into your PSN account to do anything, that means you'll be blocked if the Internet is out.

This is entirely different on the PS3, as it allows you to activate two unrestricted consoles.
