Password Generator
Generate cryptographically secure passwords with Web Crypto API. Custom length, character sets, passphrase mode, and real-time zxcvbn strength analysis.
How to Use Password Generator in 3 Steps
- Configure. Choose password length (8-128), character sets (uppercase, lowercase, digits, symbols), and mode (random, passphrase, or pronounceable).
- Process. Click Generate — the Web Crypto API produces a cryptographically secure password with a live zxcvbn-style strength score and entropy calculation.
- Export. Copy the password with one click. Nothing is stored, logged, or sent to any server.
Why Password Generator on Pixlane
Password generation is needed when creating accounts, setting API keys, rotating credentials, or anywhere a strong unique secret is required. Pixlane uses crypto.getRandomValues() — the browser's cryptographically secure random number generator — exactly the same primitive used for session tokens and encryption keys in banking and enterprise systems.
- Cryptographically Secure — Uses Web Crypto API crypto.getRandomValues() — the same primitive used for TLS session keys. No Math.random, no patterns, no predictability.
- Real-Time Strength — Built-in zxcvbn-style analyzer shows entropy bits, crack-time estimate, and visual strength meter as you tweak options.
- Privacy First — Passwords are generated 100% in your browser. Never transmitted, never stored, never logged. Even we can't see them.
- Multiple Modes — Random (classic), passphrase (Diceware-style readable), or pronounceable — pick what fits your threat model and memorability needs.
Frequently Asked Questions
Are generated passwords truly random?
Yes. The tool uses crypto.getRandomValues() from the Web Crypto API — the browser's cryptographically secure random number generator (CSRNG). This is the same primitive used for TLS session keys and encryption.
What is zxcvbn strength analysis?
zxcvbn is an open-source password strength estimator developed at Dropbox that detects common patterns, dictionary words, dates, keyboard walks, and leet substitutions. It provides a realistic crack-time estimate instead of naive entropy.
Are my passwords stored anywhere?
No. Generation happens entirely in your browser using native Web APIs. Passwords are never sent to a server, never logged, never cached beyond your current session. Closing the tab erases them.
What length and character set should I use?
For online accounts: 16+ characters with all sets enabled gives ~100 bits of entropy, resistant to all realistic brute-force attacks. For master passwords and encryption keys: 24+ characters. For memorable passphrases: 5-6 random words is equivalent to ~80 bits.
