Question 1

What specifically makes a password weak, beyond a generic score?

Accepted Answer

Specific weaknesses: (1) Length under 12 characters — every additional character multiplies the search space exponentially. (2) Dictionary words — even with substitutions (p@ssw0rd), these are in attacker wordlists. (3) Predictable patterns: sequential numbers (123), keyboard walks (qwerty), repeated characters. (4) Personal information (birth years, names) that can be guessed from public data. (5) Reuse across sites — a breach of one site exposes all others.

Question 2

How long would it take a computer to crack my password?

Accepted Answer

This depends entirely on the attack method and hardware. A modern GPU can test billions of simple passwords per second in an offline attack. An 8-character password with letters, numbers, and symbols has about 218 trillion combinations — which sounds huge but can be cracked in hours with specialized hardware. A 16-character random passphrase is estimated to take billions of years with current technology.

Question 3

Is my password safe to enter in this tool?

Accepted Answer

Yes — this tool analyzes your password entirely in your browser. It is never transmitted to any server, never stored, and never logged. You can verify this by disconnecting from the internet before typing and seeing that the analysis still works in real time.
