Best Practices for Secure Password Generation
Why entropy and character diversity matter for your security.

핵심 요점
- Length is often more important than complexity for entropy.
- Avoid common patterns and predictable sequences.
Understanding Entropy
Password entropy measures how unpredictable a password is. Higher entropy means it's harder to guess via brute force.
Adding just one more character can increase security exponentially.
Generation Tips
Use a mix of uppercase, lowercase, numbers, and symbols.
Avoid 'look-alike' characters like '1' and 'l' if you're writing it down.
Never reuse passwords across different services.
자주 묻는 질문
Is a 12-character password enough?
For most users, 12-16 characters with mixed types is a good balance.
Should I use symbols?
Yes, they significantly increase the search space for attackers.
