My iPhone 5 keeps asking me for my apple id password, sometimes for no reason, and when i put the correct password in it will keep asking for the password over and over until a message pops up saying apple id password is invalid. Ive changed the password and that didn't help, tried can't do anything that requires the password because the phone keeps rejecting it, as in it's asking me to sign in, doesn't say my password is wrong imminently, keeps asking me to sign in. anything would be helpful.
