Strong Password Generator

Create a cryptographically secure, unique password in one click. Generation happens right in your browser with the WebCrypto API — nothing is sent to a server, nothing is stored, and no account is needed.

Recommended: 12+ characters for strong protection.
A guarantee is placed on every selected type, then the rest is filled randomly.
Removes characters that are easy to confuse, like 0/O and 1/l/I — useful when typing on a phone.

How it works

Three steps, under 30 seconds.

Step 1
Set your options

Choose a length from 8 to 64 characters and tick the character types you want — uppercase, lowercase, numbers and symbols.

Step 2
Generate locally

Your browser picks every character at random using crypto.getRandomValues(). No keystrokes or results ever leave your device.

Step 3
Copy & use it once

One tap copies the password. Paste it into the new account form, then store it in your password manager so every site gets its own key.

Why you can trust it

Built for people who take password hygiene seriously — ideal when you are setting up or rotating an account in Germany or anywhere else.

🔒
Cryptographically secure

Every character comes from the browser’s WebCrypto CSPRNG using uniform rejection sampling — no weak Math.random() shortcuts.

🕵️
Zero servers, zero tracking

The page is fully static after load — open the DevTools Network tab and generate a password: no requests fire, and nothing is stored or logged.

📏
Entropy you can see

A live strength meter shows the password’s entropy in bits and an estimated offline crack time at 10 billion guesses per second.
