Not a platform, not a working platform! Make it FOREVER IN THE MOBILE VERSION OF THE APPLICATION A ONE-TIME PASSWORD, OTHERWISE PEOPLE LOSE ACCOUNTS BECAUSE OF YOU! And you just make updates. At the very least, if you change something in the mobile versions of the application, YOU DELETE THE ONE-TIME PASSWORD OR ADD TO DELETE IT! Is it the point then in the mobile versions of the application? I may have lost my account forever because of you!
