Is PS4 account sharing safe?

[Garrett]

I've read a little bit but still don't really understand.. my Sister has just picked up a PS4 & I've given her my account details so she could DL whichever of the 50+ games on my account she wants to. I've been told though, that this is not allowed & if discovered by Sony your account will be terminated and you can kiss goodbye to all your games.
She hasn't started downloading anything yet.. will we be OK or should I ask her to delete my account?

I have friends who share across the PS4 and the ONE, and have had no issues. I don't know of the details of it all, as I don't have the newer systems, but they play all the time and they are sharing accounts.
