Create 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.
Add a new phone authentication method. A user may only have one phone of each type, captured in the phoneType property. This means, for example, adding a mobile
phone to a user with a preexisting mobile
phone will fail. Additionally, a user must always have a mobile
phone before adding an alternateMobile
phone.
Adding a phone number makes it available for use in both Azure multifactor authentication (MFA) and self-service password reset (SSPR), if enabled.
Additionally, if a user is enabled by policy to use SMS sign-in and a mobile
number is added, the system attempts to register the number for use in that system.
This API is available in the following national cloud deployments.
