Password
Generator.
Generated with crypto.getRandomValues — your browser's cryptographic random source, not Math.random. Nothing is sent anywhere, and nothing is stored.
Why length beats complexity
The number under the password is its entropy — how many bits of genuine randomness it carries, computed as length × log₂(pool size). It is the honest measure, because it describes how much work an attacker has to do rather than how complicated the password looks to a human.
Adding one character to a 26-letter password multiplies the work by 26. Swapping an a for an @ multiplies it by nothing at all — every cracking dictionary has known that substitution for decades. That is why the meter here moves much further when you drag the length slider than when you tick another character set.
The crack estimate assumes an offline attack at 100 billion guesses per second, which is a fast GPU rig against a weak hash. Against a properly slow hash it would take far longer — the number is deliberately pessimistic.
Frequently asked questions
What does Password Generator do?
Strong passwords with custom length, charset and previewer. The whole thing runs in your browser tab, so it is ready the moment the page finishes loading.
Is Password Generator free to use?
Yes. Password Generator is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
