What Is SMS Verification and Why Does It Matter
SMS verification checks a user’s identity by sending a one-time password (OTP) to their phone via text message. The user enters the SMS OTP to complete login, registration, or a sensitive action.
Passwords alone are no longer enough because cyber threats, account takeovers, and identity fraud keep increasing. SMS OTP verification adds an extra layer of security while keeping the user experience simple and fast. Our OTP SMS service sends secure time passcode OTPs through text messages. This helps businesses prevent fraud and keep verification quick and easy.
