You have certainly experienced a 2FA SMS authentication recently. 2FA is an increasingly common and popular authentication system these days. It is a type of authentication that is often used alongside the standard password in two-factor authentication (2FA). Why is 2FA used, how does it work and is it really safe? We’ll go into more detail in this article!
What is SMS Two-Factor Authentication (2FA)
Let’s start with a good understanding of the concept and utility of dual-factor authentication. The purpose of 2FA via SMS is to ensure that the person who is trying to access an account or perform a transaction is the person they claim to be.
Indeed, SMS authentication is a kind of proof of identity often used for a more secure authentication than a simple password. In SMS authentication, the user provides a code that was sent to his phone via SMS as proof of his identity. As the mobile phone is a more personal element, SMS authentication provides a second identity factor.
How Does SMS 2FA Work?
The SMS 2FA consists of sending a short single password (OTP) to the user by text message. When a user connects to a website or application, Dual Factor Authentication (2FA) is triggered. While logging in, the user automatically receives an SMS to their mobile phone number with a unique numeric code. Then the user logs in online using this unique code. The connection is secure! In short, 2FA authentication via SMS looks like this:
- The user enters their username and password on the site or application
- He receives a unique code on his mobile phone via SMS if the information is correct.
- The user enters the code, to access their account or make a transaction.
- Note that the unique code expires after a set period, usually two minutes or less.
So, the 2FA via SMS process significantly reduces the possibility of online data being compromised as access to the account is limited to a password multiplied by verification via personal phone.
Is two-factor authentication secure?
Yes, 2FA authentication via SMS is super secure. However, it’s not foolproof. (In fact, nothing is.) Like many security systems, there are certain vulnerabilities.
First, it is important to have a fairly complex basic password and avoid words that are too simple or basic. Then change your passwords regularly, every month or every two months, and put a reminder to change your passwords. Also, Google offers a set of backup codes that are kept in a safe place. Facebook and Apple also offer efficient backup processes.
