What could happen if you use the same password for multiple sites?

Using the same password for multiple sites creates a significant security risk. If one site suffers a data breach and your password is stolen, attackers can use that same password to gain access to any of your other accounts on different sites where the password is used. This is particularly concerning if you have accounts that contain sensitive information, such as financial data or personal details. The potential for widespread unauthorized access arises because many people tend to reuse passwords across multiple platforms for convenience. Therefore, maintaining unique passwords for each account is vital for protecting your online security and privacy.
