What is SMS Two Factor Authentication?
SMS two factor authentication (2FA) is a widely used method of digital authentication that enhances account security alongside the traditional password and login protection. It involves the delivery of a short one-time password via text message, which is then required to access the user’s account. One key advantage of SMS 2FA is that it doesn’t rely on internet access, making it a convenient option for users who may not have consistent online connectivity.
A one-time password (OTP) is a security mechanism used to authenticate users on a digital platform. Unlike regular passwords that remain the same until changed, an OTP is generated for each authentication attempt and expires after the session begins or after a short period. This makes it ineffective for potential misuse by attackers, as it cannot be used again to gain unauthorized access.
While SMS 2FA offers convenience and speed, it also prioritizes security. Although there are some concerns regarding potential interception, the likelihood of such incidents is relatively low. The generation and transmission of SMS notifications occur offline via the cell network, which reduces the chances of in-transit interception compared to other methods like email or web-based authentication. However, additional security measures, such as incorporating an extra knowledge factor, is worth considering to further safeguard against specific risks like SIM swapping or SMS interception.
SMS 2FA is the most popular solution for a multitude of reasons. First and foremost, it is highly regarded due to its ability to be easily implemented. With minimal effort and configuration, organizations can seamlessly enable SMS 2FA for their users, ensuring enhanced security without disrupting their existing workflows.
Affordability is another crucial factor contributing to the popularity of SMS 2FA. Compared to other authentication methods, SMS-based solutions are often more cost-effective, making them accessible to organizations of varying sizes and budgets. This affordability factor allows businesses to prioritize security without incurring significant financial burdens.

An advantage of SMS 2FA over other authentication methods is that it does not require the user’s phone to have internet access. This gives SMS-based 2FA an edge over other methods that rely on online connectivity. Users can still complete the authentication process even without an internet connection, ensuring accessibility and convenience.
How does SMS 2FA provide an additional level of protection?
SMS 2FA provides additional protection by requiring a short one-time password to be sent to the user via text message. This one-time password is necessary to log in and access the user’s account. It adds an extra layer of security beyond the standard password and login protection.
What is a flash SMS and how does it enhance security?
A flash SMS is a type of SMS that shows up on the recipient’s screen for one-time viewing instead of being stored in the SMS inbox. It enhances security by not storing the security code on the recipient’s handset. This mitigates the risk of unauthorized access since the code is not stored and cannot be retrieved from the recipient’s device.
What happens after the user receives the authentication PIN code?
After receiving the authentication PIN code, the user types it into the application’s form to confirm their identity and gain access to their account and information. This step serves as a confirmation mechanism to ensure that the user is authorized to access their account.
How is the user’s identity confirmed during the SMS two-factor authentication process?
The user’s identity is confirmed by entering the authentication PIN code received via SMS into the application’s form. This step ensures that the user is in possession of their mobile phone and can receive the code, adding an extra layer of security to confirm their identity.
Benefits of SMS 2 Factor Authentication
How does SMS authentication help defend against phishing attacks?
SMS authentication serves as a defense against phishing attacks by providing a second factor of authentication. Even if a scammer obtains sensitive information, such as passwords or usernames, they will not be able to gain access to the victim’s account without the authentication PIN received via SMS. This alerts the customer to a potential phishing attack when they receive a 2FA text message without attempting to log in.
How does SMS authentication help mitigate the costs of delivering authentication codes?
SMS authentication ensures that users won’t retry immediately after receiving a notification, mitigating the costs of delivering authentication codes. Each retry could potentially add to the cost, but with quick and successful delivery, there is no need for immediate retries.
What specific security measures are taken to protect against interception and fraud?
SMS notifications are generated and sent offline via the cell network, which reduces the chances of interception during transit. Additionally, using a flash SMS can add an extra layer of security by not storing the security code on the recipient’s handset.
How easy is it to set up SMS authentication?
SMS authentication can be set up using the same SMS API used for customer communication, making the setup process simple and convenient. Users do not need to install any additional apps or extensions.
How fast is the delivery of SMS authentication codes?

How can users be onboarded to an authenticator app?
Users can be onboarded to an authenticator app by following a few simple steps. First, they need to enable Two-Factor Authentication (2FA) for the desired service they want to use the authenticator app with. This can usually be done through the account settings of the service.
Once 2FA is enabled, the service will provide a QR code that needs to be scanned using the authenticator app on the user’s mobile phone. This QR code contains the necessary information to set up the service within the app.
For example, if a user wants to set up Google Authenticator for their Facebook login, they would enable 2FA in their Facebook settings. Facebook will then generate a QR code that can be scanned via the Google Authenticator app.
Scanning the QR code adds the service, in this case, Facebook, to the user’s authenticator app. This enables the app to generate a unique 6-digit code for each login attempt.
From that point on, whenever the user wants to log in to Facebook, they simply need to enter their password as usual and then open the authenticator app. The app will display the 6-digit code specifically for the Facebook account. The user then enters this code into the designated 2FA textbox on the Facebook login page.
Some authenticator apps offer an additional convenience feature in the form of push notifications. These apps can send a push notification to the user’s device whenever a login attempt occurs. This eliminates the need for the user to search for the account in the app manually. Push notifications tend to arrive quicker than text messages, providing a faster and more seamless user experience.
By following these steps, users can easily onboard themselves to an authenticator app and enjoy the added security provided by Two-Factor Authentication.
Enhanced Security
What are the advantages of using TOTP-based authentication?
TOTP-based authentication, offered by 2FA mobile apps, provides additional security compared to SMS-based authentication. The advantages include the use of time-based one-time passwords that expire after a specific time, the elimination of SMS vulnerabilities, and the reduced chance of interception due to the limited data transmission. These factors make the authentication process more secure and less prone to unauthorized access.
What vulnerabilities are avoided by using a 2FA app instead of SMS?
Using a 2FA app instead of SMS avoids vulnerabilities associated with the SS7 network. SMS-based authentication relies on the SS7 network, subject to vulnerabilities and attacks. 2FA apps, on the other hand, generate TOTPs independently and transmit limited data, making them more secure and immune to SS7 vulnerabilities.
How does the independent generation of TOTPs enhance security?
The independent generation of TOTPs enhances security by reducing data transmission. Since the TOTPs are calculated separately by the authenticator app and the service is accessed, the amount of data transmitted is limited. This lowers the chances of anyone intercepting the code and adds an extra layer of security to the authentication process.
How are TOTPs generated and transmitted?
TOTPs are calculated independently by the authenticator app and the accessed service. The authenticator app and the service use the same algorithm to generate the TOTPs, ensuring synchronization. Only the user-entered TOTP is transmitted to the online service’s API for verification.
How do 2FA mobile apps like Google Authenticator differ from SMS-based authentication?
While SMS authentication relies on SMS PIN codes, 2FA mobile apps use six-digit one-time passwords (TOTP) that expire after a specific time. This design is inherently more secure and less vulnerable to certain attack types, including those exploiting the SS7 signaling protocol vulnerabilities prevalent in cellular networks.
These time-based one-time passwords are independently calculated by both the authenticator app and the accessed service. As a result, they are not susceptible to the SS7 vulnerabilities that have raised concerns regarding SMS security. Only the user-entered TOTP is transmitted to the application programming interface (API) by the online service, verifying whether the correct TOTP was entered before granting access.
By generating the TOTPs independently, there is minimal transmission of data. Consequently, the chances of interception and unauthorized access to the authentication code are significantly reduced. This inherent design ensures a higher level of security by limiting data delivery.
In comparison, the SMS authentication process involves the user entering a mobile phone number into the application’s form, receiving an authentication PIN code via an SMS message, and typing it into the application’s form to confirm their identity and gain access to their account and info.

Phishing involves tricking customers into revealing their sensitive information, such as passwords, user names, social security numbers etc. through either emails or other online communication. SMS 2 factor authentication helps to defend from these phishing attacks. With SMS 2FA, even if a scammer manages to obtain the sensitive information above, they will not be able to gain access to the victim’s account. When a customer receives a 2FA text message, but did not attempt to log in, this is instantly a red flag notifying the customer that they may be a target of a phishing attack.
SMS authentication offers a multitude of benefits for banks and their customers, providing an additional layer of security to the traditional username and password authentication. By implementing SMS authentication, banks can ensure that only authorized users are able to access their accounts, effectively combating the risk of sensitive information and accounts being compromised. This two-factor authentication strategy serves as a powerful defense against fraudulent activities, particularly phishing attacks which are prevalent in the banking industry.
