Create strong, secure, random passwords instantly. Customize length, character types, and generate multiple passwords at once. Check password strength in real-time — free, no signup required.
Create uncrackable passwords with enterprise-grade randomness — completely free and private.
Uses cryptographically strong Math.random() with entropy from multiple sources to ensure passwords are genuinely unpredictable — not pseudo-random patterns.
Generate passwords from 4 to 64 characters. Longer passwords are exponentially harder to crack — each additional character multiplies the possible combinations.
Toggle uppercase, lowercase, numbers, and symbols on or off. Some sites have specific requirements — customize your password to match any policy.
See exactly how strong your password is with our visual strength indicator. Color-coded from red (weak) to green (uncrackable).
Generate 5 strong passwords at once. Perfect for setting up multiple accounts, rotating passwords, or creating a batch of secure credentials.
All generation happens in your browser. Passwords are never stored, transmitted, or logged anywhere. Your generated passwords stay completely private.
Passwords are generated using cryptographically strong randomization. A 20-character password with all character types enabled has approximately 94^20 possible combinations — that's more than the number of atoms in the observable universe. According to NIST guidelines, passwords of this complexity are effectively uncrackable with current technology. However, no password is secure if it's reused, shared, or stored insecurely.
We recommend at least 16 characters for general use, and 20+ characters for critical accounts (email, banking, password managers). Here's why: an 8-character password can be cracked in minutes. A 12-character password takes years. A 16-character password takes billions of years. Every additional character makes your password exponentially stronger. Enable all character types for maximum security.
No. Absolutely not. All password generation happens entirely in your browser using client-side JavaScript. Generated passwords are never sent to any server, never stored in any database, and never logged. The password disappears from memory when you refresh the page or generate a new one. We have no way to see, access, or recover passwords you generate — because they never leave your device.
Yes, strongly recommended. Strong generated passwords are excellent — but they're also impossible to remember. A password manager like Bitwarden, 1Password, or LastPass securely stores all your generated passwords behind one master password. This means you only need to remember one strong password (your master password) while every other account gets a unique, uncrackable generated password. This is the gold standard for personal cybersecurity.
A strong password has four key characteristics: (1) Length — at least 16 characters, preferably 20+. (2) Complexity — a mix of uppercase, lowercase, numbers, and symbols. (3) Unpredictability — no dictionary words, names, dates, or patterns. (4) Uniqueness — never reused across different accounts. Our generator handles all four automatically. The strength meter shows you at a glance whether your password meets these criteria.
