Password Attacks and Defense Fundamentals

Password attacks remain common because many users reuse weak credentials across multiple services.

Brute force tries many guesses rapidly, while credential stuffing uses leaked username-password pairs from previous breaches.

Defenses start with long unique passwords, but should also include multi-factor authentication and login rate limiting.

"Strong passwords help. Layered defenses protect."

Security teams should monitor suspicious login patterns and alert users when unusual authentication behavior is detected.

Using a password manager is one of the simplest high-impact improvements for most people.
