What Is Credential Stuffing?

Credential stuffing is an attack that uses stolen username-and-password combinations from one service to attempt access to accounts on other services. Certification exams frequently connect this technique with password reuse because the attack succeeds when a person uses the same credentials across multiple websites or applications. Attackers may automate thousands of login attempts and then exploit successful access for fraud, data theft, account takeover, or additional credential collection. Defenses include unique passwords, password managers, multifactor authentication, breached-password detection, login-rate controls, device and location analysis, and alerts for unusual authentication patterns. When investigating suspected credential stuffing, defenders should identify affected accounts, terminate active sessions, reset credentials, review account changes, and determine whether the compromised password was reused elsewhere.
