Very strong~104 bits of entropy
Generate strong random passwords with a strength meter.
Your vote is saved on this device only.
The Password Generator creates strong, random passwords using your browser's built-in cryptographic randomness (crypto.getRandomValues), not predictable software shortcuts. Set the length anywhere from 8 to 128 characters, toggle lowercase, uppercase, numbers, and symbols on or off, and a live strength meter shows the estimated bits of entropy so you know exactly how hard each password is to crack before you commit to it.
It is built for anyone tired of reusing the same weak password: developers seeding test accounts, admins rotating credentials, or anyone signing up for a new service. The tool is free and runs entirely in your browser, so the passwords are generated on your device and never sent anywhere. You can produce up to ten at once and copy any of them with a single click.
No. Everything runs client-side in your browser using the Web Crypto API, so each password is created on your device and is never uploaded, stored, or transmitted.
They use crypto.getRandomValues, the browser's cryptographically secure random number generator, which is far stronger than ordinary Math.random and suitable for real credentials.
Entropy estimates how unpredictable a password is, calculated from its length and the size of the chosen character set. Higher bits mean exponentially more guesses are needed to crack it; aim for 80 bits or more.
Short lengths or selecting only one character set lower the entropy. Increase the length and enable more character types, such as symbols and numbers, to reach a strong rating.
Yes. Use the 'How many' slider to create up to ten passwords in a single batch, each with its own copy button.
