Trying to enable Keychain on my Mac, iPad and iPhone. When I hit enable it says Approve with Security Code. I enter a 4 digit code which I think is correct, although I don't recall making one. It then goes to a Verification Code screen and says it is sent to my phone number (1-***-***-**22 [and my last 2 are 22]) and asked for a 6 number code. Is it supposed to send me a text message? I don't get anything and have no way of entering the code. I have tried a dozen times and at least a couple on each device but nothing happens. I even checked my iTunes account and my phone number is correct. Running iOS 8, Yo DP8 and Drive. What am I doing wrong?
