Why Password Strength is Measured in 'Entropy'

In the world of cyber security, a password isn't "strong" just because it has a capital letter and a symbol. Strength is measured by Entropy—a mathematical calculation of how many guesses it would take a computer to "brute force" your credentials. This Password Strength Meter calculates the bits of entropy in real-time to give you an objective security score.

The anatomy of a 'Military Grade' Password

A password that takes trillions of years to crack usually follows three rules:

• Length is King: Every character you add increases the complexity exponentially. A 16-character password is millions of times stronger than an 8-character one.
• Character Diversity: By mixing uppercase, lowercase, numbers, and symbols, you increase the "pool size" that an attacker has to guess from.
• Zero Predictability: Avoid dictionary words, birthdays, or keyboard patterns (like "qwerty"). Our Random Password Generator uses cryptographically secure math to ensure complete randomness.

3 Tips for Managing Secure Passwords

1. Use a Password Manager: You shouldn't have to remember "g7#9K!pL2mN5". Use a tool like 1Password, Bitwarden, or iCloud Keychain to store your generated secure strings.
2. Enable MFA: Multi-Factor Authentication is your second line of defense. Even if someone guesses your "Military Grade" password, MFA keeps them out.
3. Change Breached Passwords: Even a strong password is useless if the service you use it on gets hacked. Use tools like 'Have I Been Pwned' to monitor your account security.
