Question 1

What makes a strong password?

Accepted Answer

A strong password has at least 16 characters, uses uppercase, lowercase, numbers and symbols, avoids dictionary words, and has high entropy (70+ bits).

Question 2

What is password entropy?

Accepted Answer

Entropy measures the randomness of a password in bits. Higher entropy means harder to crack. It's calculated as log2(pool_size ^ length). Aim for 80+ bits.

Question 3

How long would it take to crack my password?

Accepted Answer

A password with 60 bits of entropy takes about 2 years at 10 billion guesses/second. At 80 bits, it would take thousands of years. This tool estimates crack time for various attack scenarios.
