Question 1

What does "time to crack" actually mean?

Accepted Answer

It assumes an attacker can compute 10^11 password hashes per second — roughly what a high-end GPU rig can do for a fast hash like MD5 or SHA-256. For slow hashes (Argon2id, bcrypt, scrypt), the actual rate is 10^4–10^6/sec, and time-to-crack is millions of times higher than what we display.

Question 2

Why does my long password score low?

Accepted Answer

Pattern detection. "P@ssw0rd1!" is 11 characters but is a known common-password variant — the search space attackers explore is far smaller than naive entropy suggests.

Question 3

Is the password I type sent anywhere?

Accepted Answer

No. The evaluation runs entirely in the page. There is no network call, no log, no remote dictionary lookup.

Question 4

What is a good entropy target?

Accepted Answer

For online accounts (rate-limited): 60+ bits. For offline-attackable secrets (key passphrases, encrypted file passwords): 80+ bits. For long-term high-value secrets (root keys, recovery codes): 100+ bits.

Question 5

Why does "trustno1" rank so badly?

Accepted Answer

Because it appears in every password breach corpus. The pattern detector recognizes common passwords and substitutes regardless of length or symbol use.
