Update phoneAuthenticationMethod

Namespace: microsoft.graph

Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Update the phone number associated with a phone authentication method.

You can't change a phone's type. To change a phone's type, add a new number of the desired type and then delete the object with the original type.

If a user is enabled by policy to use SMS to sign in and the mobile number is changed, the system will attempt to register the number for use in that system.
