  • Real-time feedback
  • Clear error messages

Password Strength Checker

  • Real-time requirement feedback
  • Color-coded indicators (✅ met, ❌ not met)
  • Password strength meter
  • Guides users to create strong passwords

Confirmation Password Matching (signup)

  • Checks if passwords match
  • Real-time feedback
  • Clear error messages

Form Submission

  • Loading state during submission
  • Error handling and display
  • Success messages
  • Prevents double-submission

User Experience

  • Submit button disabled until form is valid
  • Clear error messages
  • Real-time feedback as user types
  • Works on mobile and desktop

Testing Done:

All validation rules tested
Error messages verified
Success messages verified

Edge cases tested

Impact:

  • Professional appearance
