How OTP SMS Works?
1. User Request: When a user requests a transaction or login, the system asks for an OTP (One-Time Password).
2. OTP Generation: The system generates a unique one-time password (OTP) in a random or alphanumeric format.
3. OTP Delivery: The OTP is sent to the user’s registered mobile phone number via SMS.
4. OTP Validation: The customer receives an OTP, which must be entered within the valid time frame (3 to 5 minutes).
5. Authentication: If the OTP matches, it must be entered within the given time limit to complete the login or transaction. After the time expires, the OTP will no longer be valid.

Strongest Features of OTP SMS Verification You Need
Instant Delivery
The OTP reaches the user within seconds, ensuring that important transactions are completed quickly.
One-Time Use Only
Every time, a different OTP is generated, and each OTP can only be used once. Once it is used, it cannot be used again.
Custom Expiry Time
To keep security important, OTP is given a limited time to be used.
Two-Factor Authentication (2FA)
Adds extra security by requiring both a password and a one-time code, keeping accounts and transactions safe from unauthorized access.
Short Message
Just like other messages, OTP SMS is very short content. It typically contains a unique code that is sent to the user’s registered phone number or email for authentication.
Any Time Request
Because the user requests it themselves for their important tasks, they can request an OTP anytime without any time limitation. This allows the user to get the OTP whenever needed, at their convenience.
