Password Check

Entropy, crack-time estimates and a Have I Been Pwned breach lookup that never sends your password.

Password

Only the first 5 characters of a SHA-1 hash are sent (k-anonymity). The password itself never leaves your browser.

Weaknesses

    Entropy assumes a random choice from the character set; real passwords are guessed with dictionaries first, which is why the weakness list matters more than the number. Use a password manager and a unique password per site.
