Yes, One-Time Password or OTP is mandatory for most online payments as an additional security measure, but it depends on the type of payment, the platform, and the regulatory requirements of your country. Here’s a detailed explanation:
Why is OTP Mandatory to be used for Online Payments?
- Two-Factor Authentication (2FA):
- OTP serves as a second layer of security after entering your payment details (like card number or account info).
- It ensures that only the account holder, with access to the registered mobile number or email, can approve the transaction.
- Preventing Fraud:
- OTP reduces the risk of unauthorized payments by adding an extra verification step.
- Regulatory Requirements:
- Many countries mandate OTP for online payments under data protection and consumer safety laws.

When is OTP Mandatory for Online Payments?
- Debit/Credit Card Transactions:
- OTP is generally required to authenticate online payments made using cards, especially for large transactions or cross-border payments.
- Some countries, like India, enforce RBI guidelines making OTP mandatory for almost all card payments.
- UPI Payments (Unified Payments Interface):
- OTP may be needed during UPI registration or while adding a new device. However, small UPI transactions usually require only a PIN instead of an OTP.
- Net Banking or Mobile Banking:
- For transferring funds or making payments, OTP is often mandatory, especially for high-value transactions.
- E-Wallets:
- Some e-wallets may require OTP when you add funds, withdraw money, or link your bank account or card.
- Recurring Payments:
- Some recurring or subscription payments might skip OTP if pre-approved by the user. However, many systems now require periodic re-authentication with an OTP.

When is OTP Not Required?
- Low-Value Transactions:
- In some regions, small-value transactions below a certain threshold (e.g., INR 2000 in India) may be processed without OTP.
- Pre-Authorized Payments:
- OTP might not be needed for transactions where you’ve already set up and authorized auto-debit (e.g., subscriptions).
- International Transactions:
- OTP may not be used for international transactions if the merchant’s payment gateway doesn’t support it. Instead, cardholder verification methods like 3D Secure or CVV might be used.
- Cryptocurrency Payments:
- Cryptocurrency platforms usually rely on internal security measures and might not always use OTP, though they often use similar 2FA systems.
Advantages of OTP in Online Payments

Disadvantages of OTP
- Delivery Issues:
- OTP may not arrive due to network issues or if the mobile number is outdated.
- Dependency on Mobile Device:
- Loss of access to the registered mobile phone may delay transactions.
- Phishing Risks:
- Scammers might trick users into sharing OTPs to steal money (e.g., OTP scams).
