What is Password Generator?
Generate strong random passwords locally. Choose length, character sets, and quantity, then copy a single password or a full batch instantly.
Why Use This Password Generator?
Password generators that run on a server could theoretically log the passwords they produce. This one generates every password locally using crypto.getRandomValues() —the browser's built-in cryptographically secure random number source. Nothing is sent over the network.
- Cryptographically secure: Uses the W3C-standard CSPRNG, not
Math.random(). - Never transmitted: Passwords are generated and displayed only in your browser tab.
- Batch generation: Generate dozens of passwords at once for bulk account setup.
- Flexible rules: Control length, uppercase, numbers, symbols, and ambiguous characters.
How to Use Password Generator
- Choose the password length and the character types you want to include.
- Open advanced options if you need multiple passwords or stricter rules.
- Generate the password list instantly in the browser.
- Copy one password or copy the full batch for account setup or handoff.

Frequently Asked Questions
Yes. The generator uses the browser's Crypto.getRandomValues() API, which is cryptographically secure.
No. Passwords are generated entirely in-browser and never sent to any server.
NIST recommends at least 12-16 characters. For high-value accounts, 20+ characters is better.
Yes. Passwords are generated using crypto.getRandomValues() —the W3C-standard cryptographically secure pseudorandom number generator (CSPRNG) built into every modern browser. This is the same source of randomness used by password managers and security applications.
