The process enhances account security by requiring a secondary verification method in addition to a password. Typically, this involves a code sent to a registered mobile device or email address, ensuring that only the legitimate account owner can gain access, even if the password is compromised. For example, upon entering login credentials on an unfamiliar device, the system prompts the user to enter a unique code received via SMS.
This security measure significantly reduces the risk of unauthorized access and potential data breaches. It is a proactive defense against phishing attempts, password theft, and other malicious activities. Its implementation has become increasingly vital as online threats evolve and the value of digital content and personal information rises.
