In the digital era, securing online transactions is very important. One-Time Passwords (OTPs) keep your credit card transactions secure. But how exactly?
This article looks at what an OTP is, how it functions in credit card transactions, and its benefits in safeguarding your financial activities.
A One-Time Password (OTP) is a unique, temporary code used for a single transaction or login session.
The purpose of OTP is to enhance security by adding an extra layer of authentication beyond regular passwords. This way only authorized users can complete transactions.
Here are the steps to a transaction process involving OTP
Initiate an online purchase and enter your credit card details.
The system prompts for OTP verification.
An OTP is sent to your registered mobile number or email.
Enter the OTP to authenticate and complete the transaction.
OTPs are time-sensitive, typically expiring within a few minutes to prevent unauthorized use.
There are several reasons why banks use OTP to verify transactions. Let’s take a look at the various ways OTPs make authentication convenient and quick.
Fraud Prevention: OTPs serve as a layer of security, making it nearly impossible for hackers or fraudsters to reuse intercepted credentials. Since OTPs expire quickly, they work as a shield against phishing and other forms of cyber fraud.
Real-Time Authentication: Verifies the legitimacy of the user in real-time. By requiring an OTP, banks, and payment platforms ensure that only the rightful cardholder can authorize transactions.
Convenience Without Compromising Security: While OTPs are a robust security measure, they are also user-friendly. Receiving an OTP via SMS or email is instantaneous, ensuring a smooth transaction process. Some applications even fetch the OTP from your messages without you having to manually type it in.
Follow these steps to keep your transactions even more secure.
Never share your OTP with anyone, including friends or family.
Use the OTP immediately upon receipt to avoid expiration.
Ensure you receive OTPs only through the official communication channels of your bank.
Keep your mobile number and email address updated with your bank to receive OTPs without issues.
