Chris from Miami, FL

Chris is having problems with the keychain password feature of his iPhone. He can't change the phone number associated with his keychain on any of his devices. Leo says that is a recovery feature that will send a recovery code via SMS to change his passwords. Leo says that second factor authentication is an important thing. If he has to get rid of the number, simply deleting it is what Apple recommends. They've also had trouble with keychain, though. Apple support may be needed and have them reset the keychain from their end.

Is there an alternative to 2nd factor authentication?
