Confirmation of entry into the service’s mail, application and personal account using SMS is a familiar action for all Internet users. They are used to SMS, they are trusted, and the sending algorithms are perfected.
But is this authorization method optimal? And if not, can it be replaced with another one and with what? We answer these questions in the article.

SMS Authorization Problems
SMS, as a whole, is a reliable communication channel with the client – they come to the device and trust them. But sms also has its drawbacks:
- Sometimes they fail. For example, when you need to enter the online bank, the SMS only arrives for a short time, the user presses the resend button, but instead of the second message, he receives the first one, in which the code is no longer relevant. This creates inconvenience for the user;
- Costly for the company. Yes, this is a familiar and well-established method of authorization. But each sent sms costs 2.5 rubles. If the service includes 10,000 people daily, then the company’s expenses for mailings will be 25,000 rubles per day. Monthly mailing costs will be from 750,000 rubles or ¾ million rubles.
Is there another authorization method that is just as secure but less expensive? We discuss this method below.
Flash Call As An Alternative To SMS Authorization
Flash Call is a method that allows users to log in to the system using a call. It is already widely used to enter applications, social networks, instant messengers, payment systems and other Internet services.
The work of Flash Call can be presented in three forms:
- The user enters his phone number in the appropriate field on the site or the application, after which he receives a call. The login code is the last four digits of the phone number.
- The user himself calls the phone number indicated on the site or in the application and thus passes authentication. There is no need to talk to someone or enter a code on the site or in the application;
- The user enters his phone number in the appropriate field on the site or in the application, after which he receives a call that must be answered. The robot will dictate the authorization code, which must be entered on the site or the application.
Since many companies already use this authorization method, many users have become accustomed to it. In addition, it has three critical advantages over SMS codes:
- Firstly, it is more secure, as it eliminates the possibility of interception of the confirmation code by third parties;
- Secondly, it allows you to save the user’s phone number in the system database, which simplifies the authorization process in the future;
- Thirdly, it is much cheaper for the company.
I want to dwell on the last point separately. Above, we have already calculated for the sms method, where, with the authorization of 10,000 people per day, the company spends 750,000 rubles per month.
When using Flash Call, one call costs 19 kopecks. That is, with the same volume of authorizations, the company will spend 57,000 rubles per month.
Authorization via Flash Call is 13 times cheaper than using SMS, and the quality of the authorization service, at the same time, does not decrease.
Call deliverability is 98%, while SMS is around 70%.
The open rate of messages reaches 80-90%. But, as we noted above, the Flash Call authorization method is already widely used, and more and more users are faced with this system every day. In addition, the site and the application information that the user will receive a call or he needs to call. The client is ready for a call from an unknown number.
In general, the statistics show that users trust authorization by call, and the quality of approval is as high as that of SMS.
Where Flash Call Authorization Is Required
Most often, it is used for:
- social networks;
- access to the mobile application;
- payment systems;
- password recovery for services and websites;
- two-step authentication;
- confirmation of write-off of bonus points on loyalty cards;
- registration in the online store and marketplace;
- logging into medical applications to access medical records and information about the patient’s health;
- access to public Wi-Fi in cafes, airports, and train stations.
And other services and applications where registration and authorization of users are required.
There is a strong competitor for SMS authorization on the market, which is likely to oust messages from the market shortly completely. In addition, Flash Call allows you to reduce authorization costs by 13 times without compromising the quality of service. And if you have a small company and receive less than 100 authorization requests per month, the service will generally be free.
