Strength Guide

Entropy is only an estimate of brute-force resistance. It does not protect you from phishing, reuse, or device compromise.

A long password reused across multiple websites is still risky, so uniqueness matters more than the headline score alone.

If you store credentials in a password manager, favor unique, randomly generated values for every account.
