A strong password is your first line of defense against unauthorized access to your online accounts. Our free Password Generator creates cryptographically secure random passwords using your browser built-in random number generator, ensuring every password is unique and unpredictable.

Customize your password by adjusting length (from 4 to 64 characters) and toggling character sets: uppercase letters, lowercase letters, numbers, and special symbols. You can also exclude ambiguous characters like 0, O, l, and 1 to avoid confusion when typing.

The password strength meter evaluates your generated password in real time, showing a visual bar and rating from Very Weak to Very Strong. Aim for at least 12 characters with a mix of character types for important accounts like email, banking, and social media.

For maximum security, consider using a dedicated password manager to store generated passwords securely. Never reuse passwords across multiple sites — even strong ones. Our generator makes it easy to create a unique password for every account in seconds.

Frequently Asked Questions

Are the generated passwords truly random and secure?

Yes. We use the Web Crypto API (window.crypto.getRandomValues), which is a cryptographically secure random number generator built into modern browsers. This is significantly more secure than Math.random() and is suitable for sensitive use cases.

What password length should I use?

We recommend at least 12 characters for general use and 16 or more for high-value accounts (email, banking, crypto). Length is the most important factor in password strength — a 16-character random password is exponentially stronger than a complex 8-character one.

Are my generated passwords stored or sent anywhere?

No. Passwords are generated entirely in your browser and are never transmitted over the internet or stored on our servers. For extra security, you can disconnect from the internet before generating.

Should I write down my passwords?

For most people, a password manager is the best solution. If you must write down a master password, store it in a secure physical location (like a safe) and never leave it near your computer. Never store passwords in a plain text file or notes app.

Why does the strength meter say my password is weak?

The strength meter evaluates entropy (randomness) based on length and character set size. Short passwords or those using only one character type score low. Try increasing length to 12+ and enabling uppercase, numbers, and symbols for a "Very Strong" rating.
