How to Create Strong Passwords — The Ultimate Guide

Password Entropy Explained

Password strength is measured in bits of entropy — the amount of randomness in a password. Each additional bit doubles the time required to crack it via brute force.

• 8 lowercase letters: ~37 bits (crackable in seconds)
• 12 mixed characters: ~71 bits (crackable in months)
• 16 mixed characters: ~95 bits (practically uncrackable with current technology)

Common Password Mistakes

1. Dictionary words: "password123" or "admin2024" — cracked in milliseconds
2. Personal information: Birthdays, pet names, addresses — easily found on social media
3. Pattern substitutions: "P@ssw0rd" instead of "Password" — attackers know this trick
4. Repeating characters: "aaaa1111" — low entropy
5. Keyboard patterns: "qwerty12345" — common and predictable

The Only Good Strategy

Use a password generator. It eliminates human bias and creates truly random, high-entropy passwords. Try our free password generator.
