As others have said, you shouldn't use separate Apple IDs, unless they're to be used by different people.
Just a heads up guys.
I have two friends who got into trouble using shared accounts it must be a silent epidemic, so know what your getting into.
Friend number one was married for over 15 years and decided to buy himself a new iPhone. He set it up himself and had no clue about iClouds sharing system. To make a long story short, as soon as he transferred his backup from itunes onto his new phone it started to transmit all of the stuff in his phone to his wife's phone. Including text messages, photos and emails.
Needless to say they soon ended up a in very expensive divorce. It was not that he was cheating on her. It was a whole bunch of small stuff were he had told his other friends stories about arguments they had and how he felt about what she had said. You would be surprised how small harmless comments can become a dagger to the heart when two years worth of them are compiled together.
Friend number two who is younger and has a very nice looking girl friend, came to me about 3 months ago asking me to setup a new iPhone 7 for him. I said "I don't want what happened to our mutual friend #1 to happen to you, so let me turn off the iCloud."
He said, no my girl friend has her own account and I want my stuff backed up. So I said ok and left the iCloud stuff and text sharing stuff on.
Two days later he calls me in a panic. How the hell do I turn off this iCloud Sh.t.
I asked him what happened! He said that his girl friend was over his house and she started to use his ipad. She had finger print access. He left the house and another girl started to text him. Anyway it got steamy and he said he came home in a Jovial mood only to find his GF all upset. She had been monitoring all the text messages in real time on his iPad!
So be very careful when you put multiple devices on the same account, make sure all the iCloud and sharing stuff is turned off. I have no idea why Apple turns it on by default but it gets a lot of people into trouble. It may be your own secondary device that gets you into hot water
