Password Generator
Generate strong random passwords or memorable word passphrases in your browser. Free, nothing sent anywhere.
🔒 Generated locally with your browser's cryptographic RNG — never sent anywhere.
Create strong passwords or passphrases locally
In Password mode, choose the length and which character sets to include — lowercase, uppercase, numbers and symbols — and optionally exclude look-alike characters (I, l, 1, O, 0). In Passphrase mode, generate a memorable string of random words (like correct-horse-battery-staple) with your choice of separator. Both use your browser's cryptographic random generator, and a live strength estimate shows the entropy in bits. Nothing is ever sent to a server.
Frequently asked questions
Are the passwords really random and safe?
Yes — they use the Web Crypto API (crypto.getRandomValues) with rejection sampling to avoid bias, the same secure randomness browsers use for cryptography, generated entirely on your device.
What is passphrase mode?
It joins several random words into a phrase that is easier to remember and type than a symbol soup, while staying strong. Add more words for higher entropy.
Is the password sent anywhere?
No. It is generated in your browser and never leaves your device — close the tab and it is gone.
