Question 1

How is password strength calculated?

Accepted Answer

Strength is scored on a 0-100 scale based on length, character variety (uppercase, lowercase, digits, symbols), entropy bits, and penalty for common patterns like dictionary words, sequences and repeats.

Question 2

Is my password sent to a server?

Accepted Answer

No. The password never leaves your browser. All analysis runs locally in JavaScript so it works offline and your credentials stay private.

Question 3

What is a good password crack time?

Accepted Answer

A strong password should take centuries to crack under modern offline attacks. Anything under a year for an offline attack means you should change it.

Question 4

How do I create a strong password?

Accepted Answer

Use 16+ characters mixing uppercase, lowercase, digits and symbols, avoid dictionary words and personal info, and use a unique password per account. A password manager is the easiest way to do this.
