Password Generator

A strong password is your first line of defense against unauthorized access to your accounts and personal information. Modern password-cracking tools can test billions of combinations per second, which means short or predictable passwords can be broken in seconds. A randomly generated password of 16 or more characters, using a mix of uppercase letters, lowercase letters, numbers, and symbols, would take centuries to crack with current technology.

This password generator uses the Web Crypto API (crypto.getRandomValues) to produce cryptographically secure random values, ensuring that the generated passwords are truly unpredictable. Unlike Math.random(), which uses a pseudo-random number generator that can be predictable, the Web Crypto API draws from the operating system's entropy source, making the output suitable for security-sensitive applications.

Best practices for password security include using a unique password for every account, enabling two-factor authentication wherever possible, and storing your passwords in a reputable password manager rather than writing them down or reusing them. Avoid using personal information like birthdays, pet names, or common words. If a service you use suffers a data breach, change that password immediately and any other accounts where you may have reused it.
