Password Generator
Generate strong, random passwords with adjustable length and character sets. Live strength meter, one-click copy, and everything runs privately in your browser.
How to use the Password Generator
Drag the slider — 16+ characters is recommended for important accounts.
Toggle lowercase, uppercase, numbers and symbols.
A fresh password appears with a strength rating in bits of entropy.
Copy it and save it in a trusted password manager.
About this tool
The password generator creates strong, truly random passwords that are far harder to crack than anything you would invent yourself. Slide to set the length, toggle the character types, and watch the live strength meter respond.
Every password is built with your browser’s cryptographic random generator and is guaranteed to include at least one character from each set you enable. Crucially, nothing is ever sent over the internet — your password is generated and stays entirely on your device.
Frequently asked questions
Is this password generator safe?
Yes. Passwords are created locally using crypto.getRandomValues and never leave your browser — nothing is transmitted, logged or stored on any server.
How long should my password be?
For important accounts, aim for at least 16 characters with a mix of types. Longer is stronger — the strength meter shows the entropy so you can see the difference.
What does ‘bits of entropy’ mean?
It measures how unpredictable the password is. Each extra bit doubles the guessing effort. Around 60 bits is solid, and 80+ is very strong against brute-force attacks.
Why does it skip lookalike characters?
To avoid confusion, it leaves out easily mistaken characters like the letter O, zero, capital I and lowercase l, so your password is easier to read and type correctly.
