Password Generator

About the Password Generator

Create cryptographically secure passwords instantly. Our Password Generator uses your browser's built-in crypto API to generate truly random passwords, not pseudo-random algorithms. Customize the length (4 to 64 characters) and choose which character types to include — uppercase, lowercase, numbers, and symbols. Each password is generated locally and never transmitted anywhere.

What Is Password Generator?

A strong password is one that an attacker cannot guess or brute-force in a reasonable time. Password strength comes from two factors: length and entropy (randomness). A truly random 16-character password drawn from a large character set has so many possible combinations that brute-forcing it is infeasible with current hardware. This tool draws randomness from the Web Crypto API's cryptographically secure pseudo-random number generator (CSPRNG), which is designed for security use and is fundamentally different from Math.random(), which is fast but predictable and unsuitable for secrets. Best practice today is to use a unique, randomly generated password for every account and store them in a reputable password manager, so you only need to remember one strong master password. Never reuse passwords across important accounts.

How to Use

1. Use the slider to set your desired password length (16 characters is recommended for most uses).
2. Check or uncheck character type options: uppercase, lowercase, numbers, and symbols.
3. Click 'Generate' to create a new random password.
4. View the password strength indicator — aim for 'Strong'.
5. Click 'Copy' to copy the password to your clipboard for pasting into a password field or manager.

Common Use Cases

• Creating a strong master password for a password manager
• Generating unique passwords for email, banking, and social accounts
• Producing secure shared credentials for team services and databases
• Generating API keys or secrets for development and testing
• Refreshing weak or reused passwords discovered in a security audit

Examples

Length 16, all character types

e.g. 7$kP9!mQvL2#xR@d

Tips & Best Practices

• Password strength is based on length and character diversity — longer with all types = strongest.
• Use at least 16 characters with mixed types for important accounts (email, banking).
• Consider using a password manager like Bitwarden or 1Password for storing generated passwords.
• Generated passwords are not stored anywhere — copy them immediately or generate a new one.
