Authentication (2FA): The security your customers expect

In this blog article, we’ll go over the benefits of identity verification via SMS and explain how to protect your customers’ data with dicomsys’ service.

For applications where two-factor authentication (2FA) is required as an additional security component, it turns out that messaging is the preferred option worldwide. Because this method is fast and easy to use, it is standardized and widely used.

With the recent increase in security breaches and data leaks, users are more concerned than ever about the security of their data. They have realized that a simple password is no longer enough. In that case, user authentication via SMS comes into play.

Two-factor authentication (2FA)

Two-factor authentication (also known as 2FA) is one of the most effective methods of protecting online accounts. By adding an extra layer of security, it ensures that people cannot access accounts that do not belong to them. Unlike single-factor (password) authentication, users must provide two different authentication factors to confirm their identity. One can be a biometric factor (facial, retina or fingerprint scan) or a possession factor. A common and convenient method for deploying 2FA is to provide tokens (PIN codes, verification codes, one-time passwords [OTPs], and the like) via SMS to the user’s mobile device. These one-time codes often expire after a short time if not used.

Special solutions are flash SMS or calls (automatic phone calls). A flash SMS appears directly on the lock screen of a cell phone and requires no interaction from the user. Such SMS are not stored in the customer’s device memory. This allows companies to use flash SMS to send confidential information to customers without worrying about the information being stored and potentially tapped. The flash call calls the user’s registered mobile number and uses it to verify the account. The call takes only a few seconds in total. There is no conversation between the user and the company. Nor do users have to enter a code manually, as verification is performed automatically in the background.


The advantage of the SMS method is that it is simple, convenient and user-friendly for the end customer – thus having a good usibilty – and works on any mobile device that can receive SMS. The given security standard is sufficient for most online applications. No additional hardware such as a code generator or authentication app is needed.

Moreover, the method does not require WLAN or data charges. In most countries, SMS charges are also integrated into the mobile phone tariff. For this reason, messaging is most commonly used for 2FA and is popular with consumers. In a survey, 75 % of respondents indicated that SMS is their preferred messaging method. In addition, 85 % of respondents said they prefer to receive an authentication code on their mobile device to generate additional security with their user ID and password for online transactions. The huge popularity of 2FA authentication via SMS is also reflected in the market. Large e-commerce companies like Amazon and eBay, as well as banks, social networks, email providers and many others are already taking advantage of its benefits.
