Verification process. How it evolves and develops

SMS authentication, also known as SMS Two Factor Authentication (2FA) and SMS One-Time Password (OTP), allows users to verify their identity through a code they receive as a text message.

This type of two-factor authentication is a second verification factor for users who can access the network/system/application through it, increasing security.

Many feel that SMS authentication is a weak form of OTP verification. Let's look at how SMS authentication works and all its pros/cons.

The number verification process. How does it work?

SMS authentication is a popular form of two-factor verification. Many companies around the world use this system. For users, verification provides an additional level of security when logging in or managing an account on different resources. Additionally, SMS 2FA is used to reset the OTP number.

How SMS verification works:

1. A user wants to log in or perform specific account management actions.
2. The website/application sends an SMS containing a unique one-time password (OTP) to the user's mobile number.
3. The user then enters a code to confirm their identity.

Global brands like Amazon, Apple, Facebook, and others use SMS authentication because it is a safe and simple method without any problems with identity verification, which many customers choose instead of other ways, e.g., verification by email and OTP.

Advantages of SMS Authentication

SMS authentication is chosen because it is convenient. Security experts call it a 2FA method that provides a balance of protection. It is much harder for attackers to hack into accounts with 2FA, and customers successfully gain access to their accounts.

SMS authentication is the most popular form of 2FA because it's easy to use: the text delivers the OTP directly to the screen. Two-factor SMS verification blocks all automated bots, 96% of mass phishing attacks, and 76% of attacks while sent to a recovered mobile number.

Two-factor authentication functions only when the user accepts it without OTP.

Evolution of data verifications. Everyday use

Here are a few reasons why SMS authentication remains so popular:

• It's more secure than a password. Any password can be cracked, complex passwords can often be forgotten, or one password login can be used for multiple resources. SMS verification minimizes the use of passwords, making life difficult for intruders.
• Convenience. Users can reuse passwords that apply to their accounts. With SMS authentication, everything is simplified because unique codes will be sent directly to the user to enter the necessary site or application quickly.
• With 2FA is better than without 2FA and OTP. Confirming identity in more than one way is better and safer than confirming an action with a single factor.

Why is SMS authentication considered risky?

Convenience and ease of use cannot hide that SMS authentication has some disadvantages, which can be avoided if used correctly.

• SIM card swapping. Sending a verification code to a personal mobile number is not always a safe idea because attackers over-sensitize SMS messages. For example, they contact the phone company, giving them the data collected about you to ask them to transfer the number. Such actions allow attackers to enter your access code or any SMS code sent to your mobile number.
• SIM card hacking. SIM card hacking and other SMS hijacking attacks are not that easy. Attackers spoof cell tower signals with SS7 systems and see data stored in personal messages.
• Lost/synchronized devices. SMS authentication alone does not always provide complete security. Given the frequency of loss with device thefts, giving your data to outsiders can be easy. Social media accounts can be opened on lost devices, along with banking apps. Synchronized devices similarly fall into the Priligy of intruders because the text message with the rest of the information can be on a smartphone, laptop, tablet, and more at once.
• Account Capture. Wireless service providers allow you to see text messages on online accounts in web portals. When such statements are not secure, attackers can quickly gain access.
• Virus attacks. Today, phishing-type virus attacks are prevalent on mobile devices and the rest of your portable technology. You can get into a harmful situation if attackers start posing as a trusted organization for you to give them personal information with passwords.
