OTP SMS
OTP SMS stands for “One-Time Password Short Message Service.” It is a highly secure and quick way to verify the identity of a user during online transactions or logins. OTPs are unique codes, usually made of 4 to 6 digits, sent to a user’s registered mobile number. These codes are valid for a short time and can only be used once, making them an excellent method for two-factor authentication (2FA).
You must have noticed that when you try to log into your bank account or make an online purchase, you receive a short code on your phone. That’s an OTP. You enter this code on the website or app to confirm that it’s really you trying to access your account or complete the transaction. If the code is correct and entered within the given time, you are allowed access. If not, it expires and becomes useless.
OTP SMS is popular because it adds an extra layer of security. Even if someone knows your password, they can’t get into your account without the OTP sent to your phone. Industries like banking, e-commerce, and fintech use OTPs widely to prevent fraud and protect user data.
To send OTP SMS, businesses use bulk SMS services and ensure high-priority delivery routes so that the message reaches the user instantly. These messages are transactional in nature and are delivered 24/7, even to DND (Do Not Disturb) numbers, as per TRAI guidelines in India.
In short, OTP SMS helps you stay safe online by verifying your identity quickly and securely. It’s simple, fast, and reliable.
Example:
“Your OTP is 948372. Please do not share it with anyone.”
This short, powerful message helps confirm your action safely.
