Password Generator
Create strong, unpredictable passwords using real cryptographic randomness. Set the length and character types, then copy — nothing is ever stored or sent.
Generate strong passwords that never touch a server
Weak, reused passwords are the number-one cause of hacked accounts. This password generator builds long, random passwords using crypto.getRandomValues — the same cryptographically secure randomness browsers use for encryption — so every password is genuinely unpredictable.
Crucially, passwords are created entirely in your browser. Nothing is sent over the internet, logged, or saved. Once you close or refresh the page, the password is gone unless you've copied it somewhere safe.
What makes a password strong?
- Length beats complexity. A 16+ character password is dramatically harder to crack than a short one, even a "clever" short one.
- Mix character types. Combining upper case, lower case, numbers and symbols expands the possibilities enormously.
- Never reuse. Use a unique password for every account so one breach can't unlock the others.
- Use a password manager. Generate a long random password here, then store it in a manager so you don't have to remember it.
Frequently asked questions
Are these passwords truly random?
Yes. They use the browser's cryptographically secure random generator, not the predictable Math.random(). Selection is unbiased across the chosen character set.
Is my password sent or stored anywhere?
No. Generation happens locally in your browser. Nothing is transmitted, logged or saved.
How long should my password be?
At least 16 characters for important accounts, using a mix of character types. Longer is always stronger.
What does "avoid ambiguous" do?
It removes easily confused characters like the letter O and the number 0, or lowercase L and the number 1 — handy when a password must be typed by hand.
