Password Generator Guide - Create Secure Passwords
Learn how to create strong, secure passwords. Understand password best practices, entropy, and how to manage multiple passwords safely.
Why Strong Passwords Matter
Weak passwords are the leading cause of data breaches. A strong, unique password for each account is your first line of defense against hackers.
Password Strength Factors
Length
Most important factor. Each character exponentially increases possibilities.
| Length | Time to Crack (Complex) |
|---|---|
| 8 chars | Hours to days |
| 12 chars | Centuries |
| 16 chars | Millennia |
Character Types
- Lowercase letters (26)
- Uppercase letters (26)
- Numbers (10)
- Symbols (~32)
Using all types: 94 possible characters per position.
Randomness
Avoid:
- Dictionary words
- Personal information
- Common patterns (123, qwerty)
- Character substitutions (p@ssw0rd)
Types of Passwords
Random Character Passwords

- Very secure
- Difficult to remember
- Best with password manager
Passphrases

- Multiple random words
- Easier to remember
- Very high entropy with 4+ words
Pattern-Based (Not Recommended)

- Easy to remember
- Also easy to guess
- Avoid for important accounts
Password Entropy
Entropy measures password unpredictability in bits:
- 40 bits: Weak
- 60 bits: Moderate
- 80+ bits: Strong
- 100+ bits: Very strong
Calculation
Entropy = logβ(possible characters^length)
12-character password using 94 characters: = logβ(94^12) = 78.8 bits (strong)
