i'm getting this message every time i try to sign in my apple ID
and i don't know what is wrong with it .?
iPhone 6, iOS 9.2.1
Had the same problem. Turned off the additional verification and I was able to get in with no problems.
Check the year, date, and time settings. Someone, 12 year old, had set his phone to sometime in 2003. I set back to automatic and everything got better.
I had the same error and an error regarding privileges on my itunes. Try reloading itunes. I went to apple.com and download itunes and problem solved.
