Bad actors may acquire access to these accounts and attempt to monitor them for SMS authentication codes if they are not secured with a trusted second factor. Taking control of an online account: Many cellular service providers allow customers to read text messages via online accounts on their web portals. Because text messages and other data may be accessed from many cellphones, laptops, tablets, and wearables, synced devices provide a chance for bad actors. Smartphones that have been lost or stolen: Relying on SMS authentication is risky given the rate at which devices are lost and stolen-and it's considerably riskier when those devices are logged into social media accounts and financial apps. Malicious actors, for example, can spoof cell phone tower signals and SS7 protocols (used to permit data roaming) in order to view the information included in private communications. SIM card hacking and other SMS or text message interceptions pose a concern as well.

This allows them to view any SMS authentication code delivered to that phone number. For example, they can contact a phone company and request that a number be changed to another phone (using personal information they have gathered on a target, such as an SSN). Here are a few dangers to be aware of: SIM swapping: While sending an authentication code to a personal mobile phone may appear secure, unscrupulous actors have discovered ways to intercept SMS communications. Cons of SMS authentication Despite its convenience and ease of use, SMS authentication has significant drawbacks, and firms must consider whether it is adequate to protect their corporate, employee, and customer data. As a result, SMS authentication is a more secure choice. Better than no 2FA: Confirming one's identity with multiple pieces of information is always more secure than confirming it with only one piece of information. SMS authentication reduces this hassle by delivering users unique numbers that they may easily enter on a website or app to verify their identities. Convenience: One of the reasons users recycle passwords is the sheer volume of online accounts they create and manage: according to our research, consumers must remember 10 passwords every day. SMS authentication reduces our reliance on passwords while also making it more difficult for bad actors to get access to and hijack accounts. Pros of SMS authentication While SMS authentication is generally discouraged, there are a few reasons why people and organizations continue to utilize it: Passwords are intrinsically weak because users tend to forget them, recycle them across several accounts, or have them stolen owing to poor storage methods (e.g., affixing them on a post-it note).

In order to acquire illegal access to an account, bad actors would have to make a user's password as well as their phone. SMS authentication, as a possession-based factor, verifies a user's identification based on something they own (i.e., a mobile phone). You've most likely seen this when using Amazon, Facebook, Google, Twitter, and other services. To acquire access, individuals simply type the code into the app or website in question. Following sign-in, the user receives a text message containing an SMS authentication code. What is the SMS authentication procedure? This authentication process is actually fairly straightforward. We'll go into why, but first, let's go through how SMS authentication works and the benefits and drawbacks of using it. It should be emphasized, however, that SMS authentication is usually seen as a weak method of verification. It is a type of two-factor authentication that frequently functions as a second verifier for users to get access to a network, system, or application and is a solid initial step toward improved security. (OTP), allows users to authenticate their identities by texting a code to themselves. SMS authentication, also known as SMS-based two-factor authentication (2FA) and SMS one-time password, is a type of two-factor authentication. What Is SMS Authentication and Is It Safe?
