SMS What are the different forms of authentication?
Simple authentication via SMS
SMS Simple authentication allows users to connect to an account without providing a username or password . After entering the connection address, an SMS OTP (One Time Password) is sent to the users mobile phone, who enters the code to connect to the application. This is a simple and fast verification method, because all you need is a mobile phone and there is nothing to remember. However, the phone is the only authentication factor , which makes this method more fragile.
Two-Factor Authentication (2FA)
SMS Two-Factor Authentication is the most popular method. It allows you to strengthen your existing security system while benefiting from easy and low-cost implementation. SMS Users enter their logins (name and password) and OTP codes are sent to further verify the connection. This two-step authentication provides bulk sms master increased security for all connections to your applications.
Multi-Factor Authentication (MFA) with SMS
Multi-factor authentication (MFA) is a multi-step (usually 3) verification method before granting access to a system, application, or data. The purpose of MFA is to strengthen security by ensuring that the person attempting to connect is who they claim to be.
This authentication is based on:
- Something you sms pay by link: send a link and increase sales know (knowledge factor: password, PIN code)
- Something that you own (possession factor: phone, computer)
- Something you are (biometric factor)
In practice, when you connect to an online banking application, for example:
- Step 1 : Enter your username and password (knowledge).
- SMS Phase 2 : Receive a verification code on your mobile phone and enter it into the application (possession).
- Step 3 : Use your fingerprint to unlock the authentication application on your phone (biometric factor).
This method is the most aleart news reliable, as it is very difficult to spoof/fake 3 verification factors at the same time. On the other hand, MFA is a lot of development effort and can be complex to activate, especially for simple connection operations, where 2 separate factors are more than enough.
