3D Secure

3D Secure is a security protocol designed to provide an additional layer of protection for online transactions. In cryptocurrency, 3D Secure helps prevent unauthorized use of credit and debit cards when making purchases or withdrawals. It requires the cardholder to enter a password or code that is only known to the card issuer and the cardholder.

This protocol adds an extra step to the transaction process, ensuring that the person using the card is authorized to do so. Without this added security measure, it is easier for fraudsters to make unauthorized transactions using stolen card information.

By implementing 3D Secure in cryptocurrency transactions, both merchants and users can have more peace of mind knowing that their transactions are better protected from potential fraudulent activities. This helps to build trust and confidence in the use of cryptocurrencies for online payments and transactions.
