About Password Generator
Why strong passwords matter
Most data breaches happen because of weak or reused passwords. A 16-character random password takes billions of years to crack by brute force. Yet most people use passwords like "password123" or their pet's name followed by a birth year. One compromised password on a breached site gives attackers access to every account that shares it.
How this generator works
This generator uses the Web Crypto API (crypto.getRandomValues) for cryptographically secure randomness — the same random number generator used by banks, encryption software, and security protocols. Unlike Math.random(), which is predictable, crypto.getRandomValues produces truly random values from your operating system's entropy pool. Each character is independently selected from your chosen character set. Nothing is transmitted — the password exists only in your browser memory until you close the tab.
Best practices
Use a unique password for every account — never reuse passwords across sites. Store your passwords in a password manager like Bitwarden (free and open source) or 1Password. Enable two-factor authentication (2FA) wherever it's available, especially on email, banking, and social media accounts. A strong password combined with 2FA makes your accounts virtually impenetrable.

Frequently Asked Questions
Is this generator truly random?
Yes. It uses crypto.getRandomValues(), the same cryptographic random number generator used by banks and security software. It draws randomness from your operating system's entropy pool, making it unpredictable — unlike Math.random() which is pseudo-random and potentially predictable.
Are my generated passwords stored anywhere?
No. Everything runs in your browser. No passwords are transmitted to any server, logged, or stored. The passwords exist only in your browser's memory. Close the tab and they're gone.
How long should my password be?
16 characters minimum for important accounts like email, banking, and cloud storage. 12 is acceptable for low-risk accounts. Anything under 8 characters is crackable in minutes with modern hardware. Longer is always better.
Should I include special characters?
Yes, if the site allows them. Special characters dramatically increase the number of possible combinations. A 12-character password with letters, numbers, and symbols has 475 trillion times more combinations than one with letters alone.
