The Mathematics of Safety
When it comes to passwords, Length > Complexity. This is due to a concept called "Entropy," which measures how much chaos or randomness is in your password.
Every character you add exponentially increases the difficulty of cracking the password. For example, adding just one character to a 12-character password can make it thousands of times harder to guess than changing an 'a' to an '@'.
Why Browser-Based is Better
This tool runs entirely on your device using JavaScript. The password is created locally in your browser's memory and is never sent over the internet. This eliminates the risk of "Man-in-the-Middle" attacks where a generated password could be intercepted.
The Golden Rules of Hygiene
- Use a Password Manager: You should never memorize your passwords. Use a tool like 1Password or Bitwarden to store them securely.
- Enable 2FA: Two-Factor Authentication adds a second lock to your door. Even if someone steals your password, they cannot get in without your phone.
- Never Reuse: If one site gets hacked (e.g., LinkedIn), hackers will try that same email/password combo on every other site (e.g., your Bank).
Frequently Asked Questions
Why are symbols important? ▼
Including symbols increases the "character set" available. If you only use lowercase letters, there are 26 possibilities per character. Adding symbols, numbers, and uppercase expands that to over 90 possibilities, making brute-force attacks significantly slower.
Is "CorrectHorseBatteryStaple" secure? ▼
Yes! This is called a Passphrase. Because it is very long (25+ characters), it has high entropy even though it uses simple words. However, computers are getting better at guessing word combinations, so adding a few numbers or symbols is still recommended.
