Password Generator
Generate strong, random passwords. Customize length and characters to fit your needs.
Free Online Password Generator
The Toolts Password Generator creates strong, random passwords that help keep your accounts safe. Every password is generated using your browser's built-in cryptographic random number generator (the Web Crypto API), which means the results are truly random and unpredictable. No password is ever sent to a server or stored anywhere.
Why You Need Strong Passwords
Weak passwords remain the leading cause of account breaches. Common passwords like "123456", "password", and "qwerty" can be cracked in under one second using modern hardware. Even seemingly complex passwords like "P@ssw0rd" appear in breach databases and are tested early in any attack. A truly random password of 16 or more characters with mixed character types is effectively uncrackable by brute force with current technology.
What Makes a Password Strong?
Password strength depends on two main factors: length and character diversity. Each additional character multiplies the number of possible combinations exponentially. A 12-character password using only lowercase letters has about 95 trillion combinations. Add uppercase, numbers, and symbols, and that same length has approximately 475 sextillion combinations. That difference makes brute-force attacks practically impossible.
How the Strength Meter Works
The strength meter evaluates your password based on length and the number of character types used. A password scores higher when it is longer and uses more character types (uppercase, lowercase, numbers, symbols). The four levels are: Weak (easily crackable), Fair (minimal protection), Strong (good for most accounts), and Very Strong (recommended for sensitive accounts).
Best Practices for Password Security
Use a unique password for every account. Never reuse passwords across services because a breach on one site would compromise all your accounts. Use a password manager to store and auto-fill your passwords so you don't need to memorize them. Enable two-factor authentication (2FA) wherever possible for an additional layer of protection. Change passwords immediately if a service reports a data breach.
Privacy and Security
This tool uses crypto.getRandomValues(), a cryptographically secure pseudo-random number generator (CSPRNG) built into every modern browser. The generated passwords never leave your device. There are no network requests, no server-side processing, and no logs. Close the tab and the password exists only where you saved it.
