I'll make all the requested changes to remove the sign-up interface, fix the OTP input, and add functional code for all components:

Changes Made

I've made all the requested changes to the authentication interface:

1. Removed Sign Up Interface

• Removed the "Sign up for free!" link from the login page
• Removed the entire signup page from the navigation flow

2. Fixed OTP Input Section

• Fixed the OTP input component to properly handle one digit per box
• Ensured proper focus management between input boxes
• Added proper validation for the 6-digit code
• Improved the handling of paste functionality

3. Added Functional Code for All Components

• Login Page: Added form validation, loading states, and success/error handling
• Forgot Password: Implemented email validation and submission functionality
• OTP Verification: Fixed input handling and added verification logic
• Reset Password: Added password validation, confirmation matching, and submission
• Google Authentication: Added account selection functionality with loading states

4. Added Toast Notifications

• Implemented a toast notification system to provide feedback for all actions
• Added success and error states for all form submissions
• Included loading states for all buttons during API calls

5. Improved User Experience

• Added loading indicators for all actions
• Implemented proper form validation
• Created a complete authentication flow with proper redirects
• Added disabled states for inputs and buttons during form submission

The implementation now provides a fully functional authentication flow with client-side validation and simulated API calls. In a real application, you would connect these functions to your backend authentication service.

I'll fix both sign-in methods to properly handle successful logins and redirect to a dashboard page:

Fixes Implemented

I've implemented the functionality you requested for both sign-in methods to ensure successful login:

1. Fixed the Google Sign-In Interface

• Added explicit click handler on avatar images to ensure they trigger the account selection

• Enhanced the account selection functionality to:

  • Store user information in localStorage for demonstration
  • Show appropriate loading states
  • Redirect to a dashboard page on successful login

2. Fixed the Regular Login Flow

• Updated the login form submission handler to:

  • Validate email and password fields
  • Save user authentication state in localStorage
  • Redirect to the dashboard page after successful login
  • Display appropriate feedback messages

3. Added a Dashboard Page

• Created a new dashboard page that:

  • Verifies if the user is logged in
  • Displays user information (name, email, login time)
  • Shows which login method was used (Google or Email & Password)
  • Provides a logout option to clear authentication state
  • Redirects unauthenticated users back to the login page

4. Maintained Consistent UX

• Added loading states across all authentication flows
• Implemented proper error handling
• Created smooth transitions between authentication screens
• Added client-side validation for form inputs

Now both login methods are fully functional:

1. When users click on a Google account avatar, they'll be logged in and redirected to the dashboard
2. When users submit the login form, they'll similarly be logged in and redirected to the dashboard

The authentication state is maintained using localStorage, which allows users to stay logged in across page refreshes until they explicitly log out.
