• Using personal information (names, birthdays)
• Simple sequences (123456, abcdef)
• Common dictionary words
• Reusing passwords across sites
• Not changing default passwords

Password Entropy Explained

Entropy measures the unpredictability of your password:

• < 28 bits: Very weak (instant cracking)
• 28-35 bits: Weak (minutes to hours)
• 36-59 bits: Moderate (days to years)
• 60-127 bits: Strong (centuries)
• 128+ bits: Very strong (virtually uncrackable)

Creating Strong Passwords

• Use at least 12-16 characters
• Combine uppercase, lowercase, numbers & symbols
• Consider using passphrases (multiple random words)
• Use a password manager to store them securely
• Enable two-factor authentication where available

Advanced Security Tips

• Change passwords after security breaches
• Never share passwords via email/text
• Be wary of phishing attempts
• Use different passwords for different accounts
• Consider biometric authentication where available
