Password Generator

By the FastFreeTools Editorial Team · Last reviewed: May 2026 · See our Editorial Policy for methodology, sourcing, and disclaimers.

Generate strong, random passwords using cryptographically secure randomness. Customize length and character types.

About this tool

Weak passwords are the leading cause of security breaches, with automated tools capable of testing billions of combinations per second. Our Password Generator creates cryptographically secure random passwords using the Web Crypto API, which provides true randomness rather than the predictable pseudo-random numbers used by simpler generators. You can customize length (8-128 characters), choose character types (uppercase, lowercase, numbers, symbols), and generate multiple passwords at once for setting up new accounts. Security experts recommend passwords of at least 16 characters with all character types for maximum entropy. The generator runs entirely in your browser — no passwords are transmitted, stored, or logged anywhere, making it safe for creating credentials for banking, email, and other sensitive accounts.

How to use Password Generator

Set your desired password length using the slider (16+ characters recommended).
Select which character types to include: uppercase, lowercase, numbers, and symbols.
Click 'Generate' to create a cryptographically secure random password.
Use 'Copy' to save the password, or generate bulk passwords for multiple accounts.

Tips & best practices

Longer passwords are exponentially stronger—each character multiplies security.
Include all character types for maximum entropy and security.
Use a different password for every account—bulk generation helps with this.
Consider excluding ambiguous characters (0/O, l/1/I) for passwords you'll type manually.

Common use cases

Creating strong login credentials for new online accounts.
Generating secure API keys and tokens for development.
Resetting passwords after a security breach or compromise.
Creating master passwords for password manager applications.

Privacy

This tool runs entirely in your browser. We do not upload, store, log, or process your input on any server. Open your browser's DevTools Network tab to verify — there is no outbound request with your data. See our Privacy Policy for details.
