Why is it risky to use the same password across multiple accounts?

Using the same password across multiple accounts poses a significant risk because if one of those accounts is compromised, all other accounts using the same password become vulnerable as well. Cyberattackers often exploit data breaches by attempting to access various platforms with credentials obtained from compromised sites. This practice is known as credential stuffing. If a user's password is stolen from one account, the attacker can easily gain access to other accounts where the same password is used, effectively leading to a domino effect of breaches across the user's digital presence. This highlights the importance of creating unique passwords for different accounts to enhance security and limit the potential impact of a single data breach.
