It’s a unique code sent automatically from the application to the end users’ mobile number. Once the code entered by the user matches with the code sent, the user profile is authenticated.
SMS OTP simplifies the process, so it’s convenient and user-friendly, sending the SMS OTP directly from an application or website to a customer’s mobile device for instant authentication.
What is SMS Authentication?
SMS authentication is a type of two-factor authentication (2FA) that uses one-time passwords (OTP) sent via text messages to verify a user’s identity. After entering a traditional password, the user receives a unique authentication code via SMS on their mobile phone. Entering this code completes the secure login process.
This method is widely used by trusted organizations and offers a cost-effective, scalable, and secure way to add multi-factor authentication (MFA) to any application or website.
