🎯 How It Works

Password Strength Analysis

The simulator evaluates passwords based on multiple criteria:

• Length - Minimum character requirements
• Complexity - Mix of uppercase, lowercase, numbers, and special characters
• Common Patterns - Detection of easily guessable sequences
• Entropy Calculation - Measures randomness and unpredictability

Password Generation

Generate secure passwords with customizable options:

• Adjustable length (8-128 characters)
• Toggle character types (uppercase, lowercase, numbers, symbols)
• Instant generation with cryptographically secure randomization
