PhoneNumber

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 to ensure that 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 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 attemptVerification() method, passing the one-time code as a parameter.

Finally, phone numbers can be used as part of multi-factor authentication. During sign in, users can opt in to an extra verification step where they will receive an SMS message with a one-time code. This code must be entered to complete the sign in process.
