In today's web applications, security is more important than ever. One of the most commonly used methods for verifying user identity is OTP (One-Time Password) authentication.
OTP-based verification helps prevent unauthorized access and enhances the security of login, registration, and transaction processes.
In this post, we’ll briefly explore how OTP authentication works and why it is essential for modern applications:
- Verifies user identity during login or signup
- Prevents fake account creation
- Adds an extra layer of security
- Commonly used in banking, SaaS platforms, and secure APIs
Developers can implement OTP using SMS, Email, or Authenticator apps depending on their use case.
I'm currently working on building secure OTP flows for backend systems and REST APIs to enhance authentication processes in modern applications.
