Secure Password Generator
Generate secure, random passwords with custom options. Free, fast, and runs 100% in your browser.
Weak passwords remain the number-one cause of account breaches. This generator uses the Web Crypto API — the same cryptographic standard used by banking applications — to produce truly random passwords. Customize length from 8 to 128 characters, choose character sets, and check the real-time strength meter. Generated passwords never leave your browser.

Frequently Asked Questions
How random are the passwords?
They use crypto.getRandomValues(), which is a cryptographically secure pseudo-random number generator (CSPRNG) — far superior to Math.random().
What length should I use?
16 characters minimum for most accounts. 20+ characters for high-security use like master passwords or API keys.
Can I exclude confusing characters?
Yes. You can exclude ambiguous characters like 0/O and l/1/I that are hard to distinguish when typing manually.
