About the Password Generator
A strong password is your first line of defense against account takeovers and data breaches. This free online Password Generator creates random, high-entropy passwords using your browser's built-in Web Crypto API, so the values are cryptographically secure and never leave your device.
You control the length and which character sets to include — uppercase letters, lowercase letters, numbers, and symbols. A live strength meter helps you gauge how resistant your password is to brute-force attacks before you copy it.
How to generate a secure password
- Choose the password length using the slider (12–16+ characters is recommended).
- Toggle the character sets you want: uppercase, lowercase, numbers, and symbols.
- A new password is generated automatically; click Generate for another.
- Check the strength indicator to confirm it is strong.
- Click Copy and paste the password into your password manager or signup form.

Strong Password Generator FAQs
Are the generated passwords secure?
Yes. Passwords are generated using the browser's cryptographically secure crypto.getRandomValues() API and are created entirely on your device — they are never transmitted or stored.
How long should my password be?
For most accounts, 12–16 characters with a mix of letters, numbers, and symbols is strong. For high-value accounts, use 20 or more characters.
Is this password generator free?
Yes, it is completely free and works right in your browser with no signup required.
Do you store the passwords I generate?
No. Everything happens locally in your browser. We never see, log, or store any password you create.
Can I use special characters?
Yes. Enable the Symbols option to include special characters such as ! @ # $ % for stronger passwords.
