A security measure commonly employed by a large retail corporation involves sending a short, system-generated alphanumeric string via SMS message to a customer’s registered mobile phone. This procedure is initiated when the system detects a login attempt from an unfamiliar device or location, or when certain transactions are being processed. As an illustration, a user attempting to access their online account from a new computer might receive a message containing a six-digit number to input on the login screen.
This authentication method adds a critical layer of protection against unauthorized access and potential fraud. Its implementation serves to confirm the user’s identity and helps prevent malicious actors from gaining control of accounts or making fraudulent purchases. The practice has become increasingly prevalent as a response to rising cybersecurity threats and the need to safeguard customer data and financial assets. The rapid adoption of such verification systems reflects the growing awareness of online security vulnerabilities.
