Authentication & Roles

Getting Started with Authentication

This guide will help you set up and test the authentication system.

Quick Start

1. Set Environment Variables

Create or update your .env file:

# NextAuth Configuration
NEXTAUTH_SECRET=<generate-with-openssl-rand-base64-32>
NEXTAUTH_URL=http://localhost:3000

# MongoDB Connection
MONGODB_URI=mongodb://localhost:27017
MONGODB_DATABASE=earthquake_catalogue

# Create default admin user
CREATE_ADMIN_USER=true
ADMIN_EMAIL=admin@example.com
ADMIN_PASSWORD=<generate-strong-temporary-password>
ADMIN_NAME=System Administrator

ADMIN_PASSWORD must be at least 12 characters when CREATE_ADMIN_USER=true.

Generate a secure secret: .. code-block:: bash

openssl rand -base64 32

2. Run the Migration

npm run migrate:auth

This will: - Create the user_roles collection - Set up authentication indexes - Create a default admin user (if configured)

3. Start the Development Server

npm run dev

4. Test the Authentication

Register a new user: - Navigate to http://localhost:3000/register - Fill in the registration form - New users are created with “Viewer” role by default
Login with admin: - Navigate to http://localhost:3000/login - Use the admin credentials from your .env file - Use the ADMIN_EMAIL and ADMIN_PASSWORD values you configured before running npm run migrate:auth
View your profile: - Navigate to http://localhost:3000/profile - See your user information and permissions
Manage users (Admin only): - Navigate to http://localhost:3000/admin/users - View all users - Change user roles - Activate/deactivate users
Request a role upgrade: - Navigate to http://localhost:3000/profile - Submit a request for Editor or Admin access - Admins review requests at http://localhost:3000/admin/role-requests
Test password reset: - Navigate to http://localhost:3000/forgot-password - Reset links expire after 1 hour - Configure EMAIL_WEBHOOK_URL to send email; without it, delivery is logged

Testing API Protection

Test with curl

# Try to create a catalogue without authentication (should fail with 401)
curl -X POST http://localhost:3000/api/catalogues \
  -H "Content-Type: application/json" \
  -d '{"name": "Test Catalogue", "events": []}'

# Login first to get a session cookie, then try again
# (You'll need to use a tool like Postman or write a script to handle cookies)

Test with Frontend

As Guest/Viewer: - Try to access /admin/users → Should redirect to home - Try to create a catalogue → Button should not appear - Can view and export catalogues
As Editor: - Can create, edit, and delete catalogues - Can import and merge data - Cannot access /admin/users
As Admin: - Full access to everything - Can manage users at /admin/users - Can change user roles - Can review role requests at /admin/role-requests

User Roles Summary

Role	View	Export	Create/Edit	Import/Merge	User Management
Guest	✓*	✗	✗	✗	✗
Viewer	✓	✓	✗	✗	✗
Editor	✓	✓	✓	✓	✗
Admin	✓	✓	✓	✓	✓

*Guest can only view public/demo catalogues

Common Tasks

Change User Role

Login as admin
Go to /admin/users
Find the user
Select new role from dropdown
Changes apply immediately

Create Additional Admin Users

Register a new user normally
Login as existing admin
Go to /admin/users
Change the new user’s role to “Admin”

Reset Password (Manual)

Currently, password reset must be done manually in the database:

// In MongoDB shell or script
const bcrypt = require('bcryptjs');
const newPasswordHash = await bcrypt.hash('newpassword123', 10);

db.users.updateOne(
  { email: 'user@example.com' },
  { $set: { password_hash: newPasswordHash } }
);

Next Steps

Read the full ``Authentication Documentation <./AUTHENTICATION.md>``_
Implement password reset functionality (future enhancement)
Add email verification (future enhancement)
Set up audit logging for security events
Configure production environment variables

Troubleshooting

“Database not initialized” error

Make sure MongoDB is running
Check MONGODB_URI in .env
Run npm run migrate:auth

“Insufficient permissions” error

Check your role in /profile
Ask an admin to upgrade your role
Ensure you’re logged in

Migration fails

Ensure MongoDB is accessible
Check database permissions
Verify environment variables are set

Security Checklist

[ ] Changed default admin password
[ ] Generated secure NEXTAUTH_SECRET
[ ] Set NEXTAUTH_URL to production domain (for production)
[ ] Enabled HTTPS (for production)
[ ] Reviewed user roles and permissions
[ ] Set up regular database backups
[ ] Configured rate limiting (already done)
[ ] Reviewed audit logs regularly

Authentication and Authorization System

This document describes the authentication and role-based access control (RBAC) system implemented in the Earthquake Catalogue Platform.

Overview

The platform uses NextAuth.js v4 with a custom credentials provider, JWT sessions, and MongoDB-backed user records. The system implements role-based access control with four distinct user roles.

User Roles

1. Admin

Full system access
User management (create, update, delete users, manage roles)
System settings and configuration
All catalogue operations (create, read, update, delete, export)
Import and merge operations

2. Editor

Create, upload, import, and merge catalogues
Update and delete catalogues
Export catalogues
Cannot manage users or system settings

3. Viewer

Read-only access to all catalogues
Export catalogues
Cannot create, modify, or delete catalogues

4. Guest

Limited read-only access to public/demo catalogues only
Cannot export or modify data

Setup and Installation

1. Environment Variables

Add the following to your .env file:

# NextAuth Configuration
NEXTAUTH_SECRET=<generate-with-openssl-rand-base64-32>
NEXTAUTH_URL=http://localhost:3000

# MongoDB Connection
MONGODB_URI=mongodb://localhost:27017
MONGODB_DATABASE=earthquake_catalogue

# Optional: Create default admin user during migration
CREATE_ADMIN_USER=true
ADMIN_EMAIL=admin@example.com
ADMIN_PASSWORD=<generate-strong-temporary-password>
ADMIN_NAME=System Administrator

ADMIN_PASSWORD is required and must be at least 12 characters when CREATE_ADMIN_USER=true.

2. Run Database Migration

Execute the authentication schema migration to set up the database:

npm run migrate:auth

This will: - Create the user_roles collection with role definitions - Add indexes to the users collection for authentication fields - Optionally create a default admin user (if CREATE_ADMIN_USER=true)

3. Change Default Admin Password

IMPORTANT: If you created a temporary admin user, change the password immediately after first login.

Current Auth Workflows

The current codebase includes these authentication workflows:

Registration at /register creates active users with the viewer role.
Login uses NextAuth credentials at /login.
Authenticated users can change their password at /change-password.
Password resets use /forgot-password and /reset-password. Reset tokens expire after 1 hour and are stored hashed in password_reset_tokens.
Users can request promotion to editor or admin from /profile.
Admins review role requests at /admin/role-requests and manage users at /admin/users.

Password reset and role-request email notifications use EMAIL_WEBHOOK_URL when configured. If no webhook is configured, email delivery is logged rather than sent.

API Protection

Protected Endpoints

The following API endpoints are protected with role-based access control:

Editor+ Required (Editor or Admin)

import { useAuth, usePermission, useIsAdmin } from '@/lib/auth/hooks';
import { Permission } from '@/lib/auth/types';

function MyComponent() {
  const { user, isAuthenticated, isLoading } = useAuth();
  const canCreate = usePermission(Permission.CATALOGUE_CREATE);
  const isAdmin = useIsAdmin();

  if (isLoading) return <div>Loading...</div>;
  if (!isAuthenticated) return <div>Please log in</div>;

  return (
    <div>
      <p>Welcome, {user.name}!</p>
      {canCreate && <button>Create Catalogue</button>}
      {isAdmin && <button>Manage Users</button>}
    </div>
  );
}

        <button>Create Catalogue</button>
      </PermissionGate>

      <PermissionGate role={UserRole.ADMIN}>
        <AdminPanel />
      </PermissionGate>

      <PermissionGate
        anyRole={[UserRole.EDITOR, UserRole.ADMIN]}
        fallback={<p>You need editor access</p>}
      >
        <EditorTools />
      </PermissionGate>
    </div>
  );
}

Protected Routes

import { ProtectedRoute } from '@/components/auth/ProtectedRoute';
import { UserRole } from '@/lib/auth/types';

export default function AdminPage() {
  return (
    <ProtectedRoute role={UserRole.ADMIN}>
      <AdminDashboard />
    </ProtectedRoute>
  );
}

Backend Usage

API Route Protection

import { NextRequest, NextResponse } from 'next/server';
import { requireEditor, requireAdmin } from '@/lib/auth/middleware';

export async function POST(request: NextRequest) {
  // Require Editor role or higher
  const authResult = await requireEditor(request);
  if (authResult instanceof NextResponse) {
    return authResult; // Returns 401 or 403 error
  }

  const { user } = authResult;

  // Your protected logic here
  return NextResponse.json({ success: true });
}

Available Middleware Functions

requireAuth(request) - Require any authenticated user
requirePermission(request, permission) - Require specific permission
requireRole(request, role) - Require specific role
requireAdmin(request) - Require Admin role
requireEditor(request) - Require Editor or Admin role
requireViewer(request) - Require Viewer, Editor, or Admin role
optionalAuth(request) - Get session if available, don’t error if not

User Management

Admin User Management Page

Admins can manage users at /admin/users: - View all users - Change user roles - Activate/deactivate users - Delete users

Programmatic User Management

import { createUser, getUserByEmail, updateLastLogin } from '@/lib/auth/utils';
import { UserRole } from '@/lib/auth/types';

// Create a new user
const user = await createUser(
  'user@example.com',
  'password123',
  'John Doe',
  UserRole.VIEWER
);

// Get user by email
const existingUser = await getUserByEmail('user@example.com');

// Update last login
await updateLastLogin(user.id);

Security Best Practices

Always use HTTPS in production - Set NEXTAUTH_URL to your HTTPS domain
Use a strong secret - Generate NEXTAUTH_SECRET with openssl rand -base64 32
Change default passwords - Never use default admin credentials in production
Implement rate limiting - Already configured for API routes
Regular security audits - Review user permissions and access logs
Password requirements - Minimum 8 characters (enforced in registration)

Troubleshooting

“Authentication required” error

Ensure you’re logged in
Check that your session hasn’t expired (30 days by default)
Verify NEXTAUTH_SECRET and NEXTAUTH_URL are set correctly

“Insufficient permissions” error

Check your user role in the profile page (/profile)
Contact an admin to upgrade your role if needed

Migration fails

Ensure MongoDB is running and accessible
Check MONGODB_URI environment variable
Verify database permissions

API Reference

See the ``API Documentation <./API.md>``_ for detailed endpoint specifications.

See user information
See role and permissions
Status: WORKING (You confirmed this!)

Test 4: Role-Based Access

Try accessing admin features:

As Viewer (current role): - Try to access /admin/users → Should redirect or show “Access Denied” - Try to create a catalogue → Button should not appear or be disabled

To test as Admin: 1. Update your role in MongoDB:

```bash mongosh earthquake_catalogue db.users.updateOne(

{ email: “test@example.com” }, { $set: { role: “admin” } }

Logout and login again
Access /admin/users → Should work
See all users and management options

Test 5: Sign Out

Click “Sign Out” on profile page
Should redirect to home or login
Try accessing /profile → Should redirect to login

Next Steps

1. Create an Admin User

To access admin features, you need an admin account:

# Option 1: Update existing user
mongosh earthquake_catalogue
db.users.updateOne(
  { email: "test@example.com" },
  { $set: { role: "admin" } }
)

# Option 2: Register new user and promote
# 1. Register at /register with admin email
# 2. Run above command with new email

2. Test Admin Features

Once you have admin role: - Go to /admin/users - View all users - Change roles - Manage user accounts

3. Test API Protection

Try making API calls:

# Without authentication - Should fail
curl -X POST http://localhost:3000/api/catalogues \
  -H "Content-Type: application/json" \
  -d '{"name":"Test Catalogue"}'

# With authentication - Need to include session cookie
# (Easier to test through the web interface)

4. Create More Users

Register additional users with different emails
Test role-based access with different roles
Verify permissions work correctly

System Architecture

Authentication Flow

User registers → Creates account with Viewer role
User logs in → Creates session with JWT token
Session stored → 30-day expiry
User accesses pages → Middleware checks authentication
User makes API calls → Middleware checks permissions
User logs out → Session destroyed

Role Hierarchy

Guest < Viewer < Editor < Admin

Permission System

Each role has specific permissions defined in lib/auth/types.ts: - Guest: Limited read access - Viewer: Full read + export - Editor: Viewer + create/edit/delete + import/merge - Admin: Editor + user management + system settings
