Broken authentication is a major security risk where flaws in session or credential management allow attackers to impersonate users. Weak passwords, poor session handling, default credentials, and storing plain‑text passwords make applications highly vulnerable. Attackers exploit these gaps through credential stuffing, session hijacking, session fixation, and URL‑based session ID exposure. Because these attacks are common, easy to execute, and highly damaging, strong defenses are critical. Key protections include enforcing MFA, avoiding default credentials, requiring strong passwords, never storing passwords in plain text, and using breached‑password detection to prevent compromised logins.
