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 multi-factor 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 will attempt to register the number for use in that system.
Permissions
One of the following permissions is required to call this API. To learn more, including how to choose permissions, see Permissions.
| Permission type | Permissions acting on self (from least to most privileged) | Permissions acting on others (from least to most privileged) |

| Delegated (work or school account) | UserAuthenticationMethod.ReadWrite | UserAuthenticationMethod.ReadWrite.All |
| Delegated (personal Microsoft account) | Not supported. | Not supported. |
| Application | Not applicable. | UserAuthenticationMethod.ReadWrite.All |
For delegated scenarios where an admin is acting on another user, the admin needs one of the following roles:
- Global admin
- Privileged authentication admin
- Authentication admin
