Question 1

Is my password safe to enter here?

Accepted Answer

Yes. All analysis runs entirely in your browser using JavaScript. Your password is never sent to any server.

Question 2

What is password entropy?

Accepted Answer

Entropy (measured in bits) estimates how unpredictable a password is based on its length and the variety of characters used. Higher entropy means a stronger password.

Question 3

What makes a password strong?

Accepted Answer

A strong password is at least 12 characters long and mixes uppercase, lowercase, numbers, and symbols while avoiding predictable patterns.

Question 4

What makes a password weak?

Accepted Answer

A password is considered weak if it is short (fewer than 8 characters), uses only one character type, contains common words or patterns like 'password123', or matches known breached passwords.

Question 5

How is password entropy calculated?

Accepted Answer

Entropy is calculated based on the size of the character pool used and the password length: entropy = length × log₂(pool size). Higher entropy means a harder-to-crack password.
