Password Generator
Generate strong, random, secure passwords
About the Password Generator
Weak passwords are the single biggest security vulnerability most people face—reusing passwords across sites, choosing memorable phrases, or using short, predictable combinations makes accounts trivially crackable. The Password Generator creates cryptographically strong, random passwords that resist brute-force attacks and dictionary attacks.
Security-conscious users generate unique passwords for every account, developers create test credentials for applications, and IT administrators provision secure temporary passwords for users. The generator uses your browser's cryptographically secure random number generator, not the predictable Math.random function.
Because password generation happens entirely in your browser, the passwords you create are never transmitted to or stored on any server. You can customize length, include or exclude character types, and generate as many passwords as needed without anyone else ever seeing them.
How to Use the Password Generator
- Set your desired password length using the slider—we recommend at least 16 characters for high-security applications, and the tool supports up to 128 characters.
- Select which character types to include: uppercase letters, lowercase letters, numbers, and special symbols. More character types increase security.
- Click the Generate button to create a random password using your selected criteria.
- Copy the password to your clipboard using the copy button, then paste it into the service where you're creating an account.
Why Use ToolForge’s Password Generator
- Uses your browser's cryptographically secure random number generator (window.crypto.getRandomValues) instead of Math.random, ensuring passwords are truly unpredictable and resistant to statistical attacks.
- All generation happens locally in your browser—passwords are never transmitted to or stored on any server, so they remain completely private.
- Customizable length up to 128 characters and selectable character types let you balance security against any platform-specific password requirements.
- One-click copy to clipboard makes it easy to transfer passwords without typing them, reducing the risk of keyloggers or shoulder surfing.
Frequently Asked Questions
How secure are the generated passwords?
The generator uses cryptographically secure random number generation (CSPRNG) via your browser's window.crypto API, which produces truly unpredictable values suitable for security applications. This is far stronger than the predictable Math.random function used by many simple generators.
What password length should I use?
We recommend at least 16 characters for high-security applications. Longer passwords are exponentially more difficult to crack—each additional character multiplies the possible combinations. The tool supports up to 128 characters for maximum security.
Should I include special characters and numbers?
Yes, including a mix of uppercase letters, lowercase letters, numbers, and special characters significantly increases password strength by expanding the possible character combinations from 26 (lowercase only) to over 90 (all types). This makes brute-force attacks much harder.
Are my passwords stored or sent anywhere?
No. All password generation happens entirely in your browser using JavaScript. No data is ever sent to any server, and the passwords are not stored in your browser's local storage or history. They exist only in memory until you copy them.
Can I generate passwords that exclude specific characters?
The current version includes all characters of the selected types. If a platform rejects certain special characters, generate a password and manually edit it, or use the character type selectors to exclude that category entirely.
