PhoneNumber
The PhoneNumber object describes a User's phone number.

Overview

The PhoneNumber object describes a phone number. Phone numbers can be used as a proof of identification for users, or simply as a means of contacting users.
Phone numbers must be verified, so that we can make sure they can be assigned to their rightful owners. The PhoneNumber object holds all the necessary state around the verification process.
The verification process always starts with the PhoneNumber.prepareVerification() method, which will send a one-time verification code via an SMS message. The second and final step involves an attempt to complete the verification by calling the PhoneNumber.attemptVerification() method, passing the one-time code as a parameter.
Finally, phone numbers are used as part of multi-factor authentication. Users receive an SMS message with a one-time code that they need to provide as an extra verification step.
