FAQ’s about SMS Authentication
What is SMS authentication and what is the difference between 2FA (2-Factor Authentication) and OTP
SMS authentication is a security measure that involves sending a one-time passcode (OTP) via SMS to verify a user’s identity. When a user attempts to log in to an account or confirm a transaction, they receive a unique code on their mobile phone. They must enter this code to complete the login process or verify the transaction. This method adds an extra layer of security beyond just a username and password. It helps prevent unauthorised access by ensuring that only someone with the registered phone can complete the process. SMS authentication is widely used for online banking, social media accounts, and other sensitive applications to protect against fraud and unauthorised access. 2FA (two-factor authentication) is a security method that uses two different forms of verification to log in, such as a password and an SMS code. An OTP is the unique code you receive as part of 2FA, usually via SMS or an authenticator app.
Is SMS authentication good for cyber security?
Yes, SMS authentication enhances cybersecurity by adding an extra layer of security. It can be implemented through two-factor authentication or OTP (One-Time Password). It requires users to enter a one-time code sent via SMS in addition to their regular password, making unauthorised access more difficult. This extra step helps protect against password theft and phishing attacks.
Why send OTP codes with SMS and how?
Sending OTP codes via SMS significantly enhances online security by providing a temporary, unique code used to verify the user’s identity during login, bank transactions, or while using two-factor authentication (2FA). This extra layer of protection ensures that unauthorized access to your accounts is prevented, even if your password has been compromised. By receiving an OTP (One-Time Password) via SMS, users can secure their data quickly and reliably. To use SMS for sending verification codes, integrate the Spryng SMS gateway into your application. Generate a unique code, send it via SMS to the user, and verify the code on submission.
