Password Generator
Generate a cryptographically secure random password, or a memorable passphrase.
About Password Generator
Our Password Generator supports two modes. Random Password creates truly random, cryptographically secure strings using your browser's built-in Web Crypto API — the same technology used in banking and security applications — with customizable length (8-64 characters) and character types. Passphrase generates a sequence of random common words (like correct-horse-battery-staple) joined by a separator of your choice, which security researchers recommend as easier to type and remember than a random string while remaining highly resistant to brute-force attacks, especially at 4+ words. Both modes include a strength indicator and run entirely in your browser — nothing is ever transmitted or stored.
Frequently Asked Questions
Yes, it uses crypto.getRandomValues(), which is cryptographically secure and suitable for generating passwords, passphrases, and keys.
Both are strong when long enough. A passphrase of 4+ random words is easier to type and remember (useful for a device unlock code or a password manager's master password), while a random password is often required by sites with strict character-mix rules.
Security experts recommend at least 12-16 characters for random passwords, or 4+ words for a passphrase. Longer is always better.
No, everything is generated entirely in your browser and never transmitted anywhere.
Yes — both modes work for any purpose, including WiFi, email, banking, or a password manager's master password.
