How to Use This Tool
Creating a strong password takes just a few steps:
- Adjust the length slider to set your desired password length (8–128 characters). Longer is stronger.
- Toggle character types — uppercase, lowercase, numbers, and symbols — to match your requirements.
- Click "Generate Password" to create a new random password using the Web Crypto API.
- Review the strength meter and entropy to ensure your password is strong enough.
- Click "Copy" to copy the password to your clipboard instantly.
Your passwords are generated entirely in your browser. No data is ever transmitted to our servers, ensuring complete privacy and security.
Frequently Asked Questions
How long should my password be?
Security experts recommend at least 12–16 characters for most accounts. For critical accounts like banking or email, use 20+ characters. The longer your password, the exponentially harder it is to crack through brute-force attacks.
Is this password generator secure?
Absolutely. All passwords are generated entirely in your browser using the cryptographically secure
window.crypto.getRandomValues() API. No passwords are sent to any server, stored, or logged. You can even use this tool offline.
What is password entropy?
Entropy measures the randomness (unpredictability) of a password in bits. It's calculated as
log2(pool_size ^ length). A password with 60+ bits of entropy is considered good, 80+ bits is very strong, and 100+ bits is practically uncrackable.
Should I include symbols in my password?
Yes! Including symbols expands the character pool from ~62 to ~94 characters, significantly increasing entropy. Some websites restrict which symbols are allowed — you can always regenerate if needed.
