Understanding OTP Authentication: How It Works & Why It’s Secure OTP Authentication is a security mechanism that generates a unique, one-time password for each login attempt, adding an extra layer of protection against unauthorized access. Unlike static passwords, OTPs expire quickly and cannot be reused, making them highly secure. OTP Authentication is commonly used in two-factor authentication (2FA), banking transactions, and enterprise security to prevent phishing and credential theft. By requiring a temporary code, it ensures that only authorized users can access sensitive accounts and data. More Info - https://www.loginradius.com/blog/identity/what-is-otp-authentication/
