What Makes a Password Strong?
Strength Factors:
- • Length (16+ characters recommended)
- • Mix of uppercase and lowercase
- • Numbers and special characters
- • Absence of common patterns
- • No personal information
- • Uniqueness across accounts
Common Weaknesses:
- • Dictionary words
- • Simple substitutions (a→@)
- • Keyboard patterns (qwerty)
- • Sequential numbers
- • Personal dates
- • Common phrases
Understanding Crack Times
Password crack time estimates are based on various attack scenarios:
- Online Attack: Limited by server response time and lockouts. Usually 100 attempts per hour.
- Offline Fast Hash: Millions of attempts per second using specialized hardware.
- Massive Cracking Array: Billions of attempts per second using distributed computing.
Frequently Asked Questions
Is it safe to test my password here?
Yes. All password analysis happens in your browser - we never store or transmit your password. For maximum security, avoid testing your actual passwords and use similar patterns instead.
How accurate are the crack time estimates?
Estimates are based on current computing capabilities and common attack methods. Actual times may vary depending on the attacker's resources and the specific hashing algorithm used to store the password.
