🔑 Password Generator
Create strong, random passwords with your browser's cryptographically secure generator — pick the length and character types and see the entropy. It all runs in your browser, so nothing is uploaded or stored.

What is a Password Generator?
A password generator builds a random string from the character types you select, giving you a login secret that's far harder to guess than anything you'd invent yourself. This one draws its randomness from your browser's cryptographically secure generator — never the predictable Math.random().
Everything runs on your device, so the password is never uploaded or stored and you can use the tool offline. Choose a length and mix of lowercase, uppercase, digits, and symbols, watch the entropy estimate, then save the result in a password manager. Longer and more varied always wins.
❓ Frequently Asked Questions
How random are these passwords?
They use your browser's cryptographically secure random generator (window.crypto.getRandomValues), the same class of randomness used for security keys — not the weak, predictable Math.random(). Each character is drawn independently from the character set you choose.
Is the password sent anywhere or saved?
No. Generation happens entirely in your browser and the password is never uploaded, logged, or stored. It runs locally, so you can even use it offline. For safe keeping, save the result in a reputable password manager rather than a note.
What length and character types should I choose?
Aim for at least 16 characters and mix lowercase, uppercase, digits, and symbols. The tool shows an entropy estimate in bits — higher is stronger. Longer passwords with more character types are exponentially harder to crack, so favour length above all.
What does the entropy figure mean?
Entropy, measured in bits, estimates how unpredictable the password is: each extra bit doubles the number of possible passwords an attacker must try. As a rough guide, 60 bits is weak, 75–80 bits is solid for most accounts, and 100+ bits is very strong.
