Password Generator
Generate strong, random passwords instantly — customizable length and character sets.
About This Tool
The TulTek Password Generator uses the browser's built-in crypto.getRandomValues() API to produce cryptographically secure random passwords. Adjust length from 8 to 64 characters, choose character sets, and get a new password instantly. The strength meter helps you gauge security at a glance.
Why Use a Random Password Generator?
Human-chosen passwords are predictable. Studies show that people reuse the same passwords across sites and rely on easy-to-guess patterns like names, birth years, and keyboard walks (e.g. "qwerty123"). These habits make accounts vulnerable to dictionary attacks, credential stuffing, and brute-force attempts.
A truly random password uses a large, unpredictable character pool. Even a 12-character password mixing upper, lower, digits and symbols yields over 475 quadrillion possible combinations — far beyond what any attacker can test in a reasonable timeframe.
TulTek's generator uses crypto.getRandomValues(), a Web Crypto API that generates cryptographically strong random numbers — the same standard used by secure applications. The generated password never leaves your browser. No server involvement, no logs, no risk.
Store generated passwords in a trusted password manager such as Bitwarden, 1Password, or KeePass. Never reuse passwords, especially for email accounts, banking, and work systems.
Frequently Asked Questions
Is this truly random?
Yes. The generator uses the Web Crypto API (crypto.getRandomValues()), which provides cryptographically strong random values — not a predictable pseudo-random algorithm.
What length should I use?
16 characters is a solid minimum for most accounts. Use 20+ for sensitive accounts like email, banking, and work systems. The strength meter guides you.
Is my generated password stored anywhere?
No. The password exists only in your browser's memory. It is never sent to any server, logged, or stored. Refreshing the page generates a new one.
