This runbook manages phone numbers as regular MFA factors (call/text verification). Important: The Microsoft Graph phoneMethods API does not offer a way to add a phone number as "MFA only" without triggering an automatic SMS Sign-In registration attempt. If the user is enabled by the tenant's Authentication Methods Policy for SMS Sign-In, Graph will automatically try to register the number for SMS Sign-In after creating or updating the phone method. If the number is already used by another user for SMS Sign-In, Graph returns a 409 Conflict with error code "phoneNumberNotUnique". However, the phone method itself (for regular MFA) is typically created or updated successfully despite this error. The smsSignInState property is read-only and cannot be controlled via the create/update request. SMS Sign-In can only be explicitly managed via the separate enableSmsSignIn and disableSmsSignIn endpoints. This runbook verifies the actual state after such errors and reports success if the MFA method was assigned, with a warning about the SMS Sign-In conflict. If the assignment truly failed, it searches for the user holding the number. ### Activate user notification This runbook can optionally send a notification email to the target user informing them that their mobile phone MFA method was added, updated, or removed by an administrator. To enable this, you need to activate user notification in the runbook customization. The json configuration for this is as follows: ```json "rjgit-user_security_set-or-remove-mobile-phone-mfa": { "parameters": { "UserId": { "Hide": true }, "NotifyUser": { "Default": true, "Hide": true }, "EmailFrom": { "Hide": true }, "ServiceDeskDisplayName": { "Hide": true }, "ServiceDeskEmail": { "Hide": true }, "ServiceDeskPhone": { "Hide": true }, "ServiceDeskPortalUrl": { "Hide": true }, "ServiceDeskTicketUrl": { "Hide": true }, "LanguageOverride": { "Hide": true }, "CallerName": { "Hide": true } } } ``` For more information on how to customize runbooks, please refer to the [Runbook Customization Guide](https://docs.realmjoin.com/automation/runbooks/runbook-customization). ### Setup regarding email sending Sending a notification email is optional and only happens when `NotifyUser` is enabled. The sender address is taken from the `RJReport.EmailSender` tenant setting. This runbook sends emails using the Microsoft Graph API. To send emails via Graph API, you need to configure an existing email address in the runbook customization. See the [RealmJoin Report Settings documentation](https://docs.realmjoin.com/automation/runbooks/runbook-report-settings) for details. ### Location User → Security → Set Or Remove Mobile Phone MFA **Full Runbook name** rjgit-user\_security\_set-or-remove-mobile-phone-MFA ### Permissions #### Application permissions * **Type**: Microsoft Graph * AuditLog.Read.All * User.Read.All * UserAuthenticationMethod.ReadWrite.All * Mail.Send ### Parameters #### UserId Object ID of the target user. | Property | Value | | ------------- | ------ | | Required | true | | Default Value | | | Type | String | #### phoneNumber Mobile phone number in international E.164 format (e.g., +491701234567). | Property | Value | | ------------- | ------ | | Required | true | | Default Value | | | Type | String | #### Remove "Set/Update Mobile Phone MFA Method" (final value: $false) or "Remove Mobile Phone MFA Method" (final value: $true) can be selected as action to perform.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.realmjoin.com/automation/runbooks/runbook-references/user/security/set-or-remove-mobile-phone-mfa.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
