Understanding Password Strength

What makes a password strong or weak.

Length

<8 chars: Very weak. 8-11: Weak. 12-15: Medium. 16+: Strong.

Complexity

Mix lowercase, uppercase, numbers, and special characters for maximum strength.

Common Patterns

Avoid keyboard patterns (qwerty), repeated characters, and sequential characters.

Dictionary Words

Common words, names, dates, and pop culture references are easily cracked.

Creating Strong Passwords

Two proven methods for generating secure passwords.

Passphrase Method

Choose 4-6 random words. Combine with spaces or special characters. Add capitalization and numbers.

Random Password Method

Generate at least 16 characters. Include all character types. Store in a password manager.

Entropy and Password Strength

Entropy is a measure of password unpredictability, typically measured in bits:

• Less than 40 bits: Very weak
• 40-60 bits: Weak
• 60-80 bits: Medium
• 80-100 bits: Strong
• 100+ bits: Very strong

The entropy of a truly random password can be estimated as: log2(C) x L, where C is the character set size and L is the password length.

Password Manager Recommendations

We strongly recommend using a password manager to generate and store unique, complex passwords for each service you use. Popular options include:

• Bitwarden
• 1Password
• KeePassXC
• LastPass
• Dashlane

Security Considerations

1. Never share your passwords: Even with this tool, your password is processed locally in your browser
2. Use unique passwords: Each account should have a different password
3. Change compromised passwords: If your password appears in a data breach, change it immediately
4. Enable MFA/2FA: Add an extra layer of security with multi-factor authentication
5. Regularly update critical passwords: Change passwords for sensitive accounts periodically
