How does this calculate strength?

The tool uses an algorithm that checks for common dictionary words, repeated patterns, keyboard layouts, and entropy to estimate how long it would take an offline attacker to crack it.

Is my password saved?

No, the analysis is executed entirely client-side. Your password never leaves your device.

What makes a password strong?

Length is the most important factor. A long phrase (e.g., a 4-word passphrase) is generally much stronger and easier to remember than a short, complex password.

What is the Password Strength?

The Password Strength tool evaluates the security of your password by analyzing its entropy, pattern predictability, and resistance to brute-force or dictionary attacks.
