Hello, if you are prompted to request a SMS verification code when logging in, it is because the system detects that the user is not logged in with a common device, SMS verification is required to ensure security.

If you are logged in on a common device, but still require SMS verification, it is recommended to check if the DingTalk version is up to date, try to upgrade the version or uninstall and reload it;

If it is already the latest version, please submit the fault with screenshots and text descriptions of the situations you encounter and submit them to the technician for troubleshooting.
