Create phoneMethod

Namespace: microsoft.graph

Add a new phone authentication method for a user. 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 pre-existing mobile phone fails. 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 attempts to register the number for use in that system.

This API is available in the following national cloud deployments.

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

Permission type	Least privileged permissions	Higher privileged permissions
Delegated (work or school account)	UserAuthenticationMethod.ReadWrite.All	Not available.
Delegated (personal Microsoft account)	Not supported.	Not supported.
Application	UserAuthenticationMethod.ReadWrite.All	Not available.

Important

In delegated scenarios with work or school accounts, the signed-in user must be assigned a supported Microsoft Entra role or a custom role with a supported role permission. The following least privileged roles are supported for this operation.

• Authentication Administrator
• Privileged Authentication Administrator

Users can't add a phone authentication method to their own account.

HTTP request

Add a phone authentication method to another user's account.

POST /users/{id | userPrincipalName}/authentication/phoneMethods

Request headers

Name	Description
Authorization	Bearer {token}. Required. Learn more about authentication and authorization.
Content-Type	application/json. Required.

Request body

In the request body, supply a JSON representation of a phoneAuthenticationMethod object. The JSON must include phoneNumber and phoneType, but not smsSignInState (which is read-only).

Property	Type	Description
phoneNumber	String	The phone number to text or call for authentication. Phone numbers use the format +{country code} {number}x{extension}, with extension optional. For example, +1 5555551234 or +1 5555551234x123 are valid. Numbers are rejected when creating or updating if they don't match the required format.
phoneType	String	Possible values are: mobile, alternateMobile, and office.

Response

If successful, this method returns a 201 Created response code and a new phoneAuthenticationMethod object in the response body.
