The danger of credential stuffing is growing—cybercriminals reuse leaked login data from past data breaches to attempt unauthorized logins across various online services. Because so many users reuse passwords, they often find valid credentials. To safeguard your accounts, you must take proactive measures that break the cycle of password reuse and enhance your account security.
