Let me read the debug logs first to check for any issues:

Good, the app is working fine. Now let me read the auth-form component to remove the email field for student sign-in/create account:

Let me read more of the auth form to see the form fields:

Let me continue reading to see the student details form:

I can see the auth form structure. The user wants to remove the email field for students in both the sign-in and create account flows. Students should only use roll number, school name, and password. Let me update the auth form and the student user creation logic:

Now let me continue reading to see where the student user is created and update that logic:

I can see that the student account is being created with email at line 155. For students, we need to generate an email internally since they don't provide one. Let me update this logic:

Now I need to remove the email field from the student details form. Let me update the JSX:

I've successfully updated the authentication system for students:

1. Removed email field from student sign-in - Students now only use roll number, school name, and password to log in
2. Removed email field from student account creation - Students only provide name, roll number, school name, and password when creating an account
3. Auto-generated student email - The system now internally generates a unique email for each student based on their roll number and school name, so the backend can still identify them uniquely
4. Maintained backward compatibility - Teachers and admins still use email-based authentication as before

Students can now have a cleaner sign-up and sign-in experience without needing to provide an email address, while the system maintains unique identification through the generated email internally.

Let me read the debug logs first to check for any issues:

Good, the app is working. Now let me read the current auth-form to understand the structure:

Let me continue reading the auth-form to see the sign-in and create account sections:

Good, I can see the sign-in section already asks for role. Now I need to:

1. Add teacher credential management to the auth library
2. Update the sign-in logic to handle teacher pre-registered credentials
3. Create a teacher records component for admins
4. Update the dashboard to add teacher records tab

Let me first update the auth library to add teacher credential functions:

Now I'll add teacher credential management functions to the auth library:

Now I'll add the teacher credential management functions:

Now I need to update the auth-form to import the teacher credential functions and use them for teacher sign-in:

Now I'll update the sign-in logic to handle teacher credentials:

Now I need to update the create account logic to handle teacher credentials. Let me find and update the create account section for teachers:

Let me continue reading to see the rest of the create account logic:

Now I'll update the create account logic to handle teachers with pre-registered credentials:

Now I need to check the sign-in form section and ensure it asks for school name for teachers. Let me read that section:

I can see the issue. The teacher sign-in form currently shows only email and password. I need to update it to show email, password, and school name. Let me update this:

Now I need to add an else clause for admins. Let me read more to see the structure:

I see the admin form is empty. Let me update it to show email and password for admins:

Now I need to create a Teacher Records component for admins. Let me create this:

Now I need to update the dashboard to include the Teacher Records tab. Let me read the dashboard to find where to add it:

Now I'll add the TeacherRecords import and add it to the ActiveTab type:

Now let me find where the navigation tabs are defined and add the teacher-records tab:

I can see where the admin tabs are. Now I'll add the teacher-records tab:

Now I need to find the switch statement where the content is rendered and add the teacher-records case. Let me read more:

I can see where to add the teacher-records case. Let me add it:

I've successfully implemented the complete teacher credential management system for the disaster management app. Here's what was updated:

Changes Made:

1. Auth Library Updates: Added TeacherCredential interface and new functions for managing teacher credentials (addTeacherCredential, getTeacherCredentialsBySchool, verifyTeacherCredential, markTeacherCredentialAsUsed, deleteTeacherCredential)

2. Auth Form Updates:

   • Teachers now sign in with email, password, and school name (matching the pre-registered credentials)
   • Teachers can create accounts only with credentials pre-registered by admins
   • Sign-in flow now properly handles role-specific fields for students (roll number), teachers (email), and admins (email only)

3. Teacher Records Component: Created a new admin interface where admins can:

   • Add teacher credentials (email and password) for their school
   • View all registered teacher credentials with their status
   • Delete teacher credentials when needed
4. Dashboard Integration: Added the "Teacher Records" tab to the admin dashboard navigation for managing teacher credentials

Teachers now follow the same pre-registration model as students, where admins must provide credentials before teachers can sign up.
