What is OTP SMS?
OTP SMS (one-time password SMS), also known as TAC in Malaysia, is a security method that sends a unique code to a user’s mobile number to verify identity during login, registration, or transactions.
How OTP SMS Works
- User requests OTP (login, payment, etc.)
- System generates a unique OTP number
- OTP SMS is sent instantly
- User enters code for verification
Why OTP SMS is Important
OTP SMS plays a critical role in modern security by ensuring that only verified users can access accounts or complete transactions.
- Prevent unauthorised account access
- Secure logins, registrations, and password resets
- Confirm payments and sensitive transactions
- Add a verification layer without introducing complex user steps
Because OTPs are time-sensitive, delivery speed and consistency directly affect user trust, completion rates, and overall platform reliability.
Common OTP SMS Use Cases
OTP SMS is most often embedded within security-critical workflows where immediate verification is required.
Common use cases include:
- User login and registration
- Password resets and recovery
- Payment and transaction verification
- Identity confirmation
In practice, businesses combine OTP SMS with other messaging services, using OTP strictly for security, while reserving bulk SMS for non-sensitive communication.
