  • Custom settings
• Customization Options:
  • Length control (8-64 characters)
  • Character types (uppercase, lowercase, numbers, symbols)
  • Exclude similar characters (i, l, 1, o, 0)
  • Exclude ambiguous symbols ({}, [], (), /)
• Security Metrics:
  • Entropy calculation
  • Estimated crack time

PIN Generation

Security Information

This application generates passwords using cryptographically secure methods:

• Secure random algorithm uses window.crypto.getRandomValues()
• Entropy calculations based on character set and length
• Crack time estimates considering modern computing capabilities (10 trillion guesses/second)

The application runs entirely in the browser with no server communication. All processing happens locally, ensuring your passwords never leave your device.
