Password Generator

In the age of automated "brute-force" attacks, having a secure password is your first line of defense. Hackers use powerful GPUs to try billions of combinations per second, making simple passwords obsolete.

Entropy: The Measure of Randomness

Entropy describes how much uncertainty is in a password. It is calculated based on the number of possible characters (L) and the length of the password (N).
Entropy = log2(L^N)

A password with 80 bits of entropy or more is considered "Very Strong" and would take trillions of years to crack with current technology.

Length vs. Complexity

Many websites require symbols and numbers, but Length is actually a much better defense against brute forcing.

• P@ssw0rd! (9 characters, complex) has ~45 bits of entropy.
• correcthorsebatterystaple (25 characters, simple) has ~100 bits of entropy.

The latter is much harder for a computer to guess and much easier for a human to remember.

Best Practices for Digital Safety

1. Use a Password Manager: Don't try to remember your passwords. Use a tool like Bitwarden, 1Password, or iCloud Keychain.
2. Unique for Every Site: Never reuse a password. If one site is breached, all your accounts are at risk.
3. Enable 2FA: Two-Factor Authentication (2FA) ensures that even if a hacker has your password, they still can't access your account without a physical token or app code.
