What Makes a Strong Password?

A strong password has several key characteristics:

Length: At least 12-16 characters (longer is better)
Variety: Mix of uppercase, lowercase, numbers, and special characters
Avoid: Common words, personal information, patterns, and sequences
Uniqueness: Different password for each account

Password Entropy Explained

Entropy measures password randomness and unpredictability. Higher entropy means stronger passwords:

Low (< 28 bits): Easily crackable, avoid for any important accounts
Medium (28-35 bits): Acceptable for low-security accounts only
High (36-60 bits): Good for most accounts including email and social media
Very High (60+ bits): Ideal for banking, crypto, and high-security accounts

Password Security Best Practices

Follow these practices to keep your accounts secure:

Use unique passwords for each account to prevent credential stuffing attacks
Aim for 16+ characters for important accounts (email, banking, crypto)
Use a password manager to generate and store strong, unique passwords
Enable two-factor authentication (2FA) whenever possible
Change passwords immediately if a service you use reports a data breach
