why password
every calculation runs inside your browser tab. nothing is sent to any server — not even anonymous telemetry.
strength updates as you type so you can iterate character by character until your password is genuinely solid.
no sign-up, no extension, no app download. open the page, test your password, close the tab.
how it works
password measures five properties of your password. each one you satisfy raises your score — and makes real-world crack time exponentially longer.
passwords under 8 characters can be cracked in seconds. length is the single most powerful lever you have.
mixing case expands the character set an attacker must search through at every position.
standard baseline — required for case-mixing to deliver its full entropy benefit.
adds 10 more symbols to the search space for every character position in your password.
over 30 common symbols. including even one multiplies the search space dramatically.
tips
a 16-character password is not twice as hard to crack as an 8-character one — it's billions of times harder. aim for at least 12 characters on every account that matters.
each type you include multiplies the search space. uppercase + lowercase + numbers + symbols turns a mediocre password into a genuinely hard target.
attackers run dictionary attacks before brute-force. "Password1!" fails immediately. a nonsense passphrase like horse-fire-tunnel-99 is far harder to crack.
if one site is breached, every account sharing the same password is at risk. use a password manager — it generates and stores unique passwords for every site.
takes 10 seconds. completely private. no sign-up required.
