Our Free Password Generator - Secure & Random Passwords is a free online security tool that creates strong, random passwords instantly — no sign-up required. In today's digital world, weak passwords are the #1 security vulnerability. Our generator creates passwords with customizable length (4–128 characters), character types (uppercase, lowercase, numbers, symbols), and advanced options like passphrase mode, exclude ambiguous characters, require all character types, and prevent repeating characters. Each password is generated using cryptographically secure randomness directly in your browser — your passwords are never stored, logged, or transmitted to any server. The built-in strength meter and entropy analysis show you exactly how secure your password is, including estimated crack time. You can also use the passphrase mode to generate memorable word-based passwords (like "correct-horse-battery-staple") that are both strong and easy to remember. The bulk generator creates up to 100 passwords at once. With the save feature, you can store passwords locally in your browser for quick access. Whether you need a password for email, banking, social media, or work accounts, this tool gives you military-grade security with zero friction. No downloads, no registration, no data collection — just instant, private password generation that works on any device.
How strong are the generated passwords? +
This Free Password Generator - Secure & Random Passwords tool generates cryptographically random passwords using the Web Crypto API. You can set length from 8 to 128 characters and include uppercase, lowercase, numbers, and symbols.
What is passphrase mode? +
Passphrase mode generates passwords from random word combinations (e.g., "correct-horse-battery-staple"), making them easier to remember while maintaining high entropy.
What does entropy mean in password strength? +
Entropy measures password randomness in bits. More bits = harder to crack. 80+ bits is strong for most uses, 128+ bits is recommended for master passwords.
Are the passwords generated in my browser? +
Yes. All password generation happens locally using the browser's crypto API. No passwords are transmitted or stored anywhere.
