Question 1

How do attackers crack passwords?

Accepted Answer

Attackers use several techniques: dictionary attacks try common words and known leaked passwords, brute force systematically tries every possible combination, rainbow tables use precomputed hash lookups for speed, and hybrid attacks combine dictionary words with common substitutions like p@ssw0rd. Modern GPUs can test billions of hashes per second against weak algorithms like MD5 or SHA-1, making short or predictable passwords trivially crackable.

Question 2

What makes a password truly strong?

Accepted Answer

Length is the single most important factor — a 16-character random password is exponentially harder to crack than an 8-character one. Use a mix of uppercase, lowercase, numbers, and symbols, but avoid predictable patterns. Better yet, use a passphrase of 4-5 random words. Never reuse passwords across sites. Enable MFA wherever possible. Use a password manager to generate and store unique passwords for every account, eliminating the need to remember complex strings.
