Ok, so, this is the situation. I have my primary account on the PS4 with my PS+ account. I want to share games with my friend, he will give me his account to play some games. So, since, from what I understand, I need to put his account as my primary account on the PS4. But since I do that, do I have to deactive as my primary account MY psn? meaning, the PS+ subscription will be affected?
Your PS+ subscription will remain unaffected. The only thing that will happen is that the other accounts in your PS4 will no longer benefit from your account's PS+ perks.
Keep in mind that:
- You can activate only one PS4™ system per account.
- When you activate a system, other users of the system can use applications and enjoy some of the PlayStation®Plus benefits of your account, even if that user is not logged in.
This means that your friend won't be able to have his account activated as primary on his PS4.
Also don't forget the following feature of having a console activated as primary:
- You can connect to your PS4™ system via the Internet using Remote Play on another device.
Even though you can deactivate this in your PS4's options I wouldn't recommend using someone else's account as a primary account on your PS4 unless you absolutely trust this person.
