Password Generator
Create genuinely random, strong passwords or memorable passphrases.
About this tool
“123456” and “password” still open millions of accounts. This generator produces genuinely random passwords — you choose the length and whether to include uppercase, digits and symbols — using your browser's cryptographic random number generator, the same quality of randomness used for encryption itself. A passphrase mode strings together common words for something you can actually remember and type.
The password is generated locally and never transmitted: nobody else sees it, including us. The strength meter shows the entropy in bits so you can judge for yourself rather than trusting a green bar.
Frequently asked questions
How long should a password be?
At least 16 characters for anything that matters, and 20 or more for your password manager and your main email account. Every extra character multiplies the time needed to crack it.
Where should I store my passwords?
In a password manager such as Bitwarden, 1Password or KeePass: a strong, unique password per site, and only one to remember. Reusing passwords is what turns one breach into ten.
Is this generator really random?
Yes. It uses the browser's crypto.getRandomValues API, designed to produce cryptographic-quality randomness, rather than the predictable pseudo-random function used by ordinary scripts.
Are passphrases safer than passwords?
A four-word passphrase is weaker than a 16-character random string, but a six-word one is very strong and far easier to type on a phone or a TV. Pick whichever you will actually use.
Is it really free, with no sign-up?
Yes — the tool is free, needs no account and has no usage limit. Processing happens locally in your browser, so your data never leaves your device.
