Frequently Asked Questions

How is password strength calculated?
Strength is based on length, character diversity, entropy, absence of common patterns, and dictionary word detection. Scores range from 0-100 considering multiple security factors.
What makes a password strong?
Strong passwords are long (12+ characters), use mixed case, numbers, and symbols, avoid predictable patterns, and don't contain dictionary words or personal information.
How accurate are crack time estimates?
Estimates assume brute force attacks and vary based on available computing power. Real attacks may use dictionaries and patterns, potentially reducing actual crack times.
Should I use special characters?
Yes, symbols significantly increase password entropy and strength. However, length is generally more important than complexity for security.
Are passphrases better than complex passwords?
Long passphrases (4+ random words) are often stronger and more memorable than shorter complex passwords. Both length and unpredictability are crucial.
