⚙️ Advanced Features

Explore advanced features including common password detection, custom scoring curves, and comprehensive security checks.

1. Common Password Detection

Check passwords against a dictionary of 500+ common passwords with leet-speak normalization.

Why It Matters

Common passwords are easily guessed by attackers
Dictionary attacks try these first
Even with substitutions (p@ssw0rd), they're still weak
Our service detects both exact and leet-speak variants

2. Scoring Curves

Compare different scoring algorithms: Linear, Logarithmic, and Step-based.

Linear Curve

Password (Linear)

Password Requirements:

How it works:

Each character adds equal value. Predictable scoring.

Logarithmic Curve

Password (Logarithmic)

Password Requirements:

How it works:

Diminishing returns for longer passwords. More realistic security modeling.

Step Curve

Password (Step)

Password Requirements:

How it works:

Threshold-based: 8, 10, 12, 16+ chars. Clear security tiers.

💡 Tip: Try the same password in all three to see how scoring differs. For example: "Test1234" vs "Test1234567890"

3. Comprehensive Security Check

All features enabled: Pattern detection, common password check, and advanced scoring.
