If users login from an unknown IP address, without an active trusted identity confirmation cookie in a browser, a verification code will be sent via SMS if the mobile number is verified. Learn how you can properly verify your mobile number.
Important: Salesforce Support is unable to perform these steps. The user account owner can verify their own mobile number or their system administrator can add the mobile with the proper format under the user detail page.
Example:
+1 5034440579
+39 5034440579
Note: As a security measure, when Users add or update mobile numbers in the Advanced User Details, they must log in again to verify their identity. As a result, unsaved changes in the app are lost. To disable this security measure, contact Salesforce Support.
