Targeted Login Pages

TL;DR

Yes, you can configure a login page to target specific users by using conditional logic based on username, IP address, user agent, or other identifying factors. This allows for custom authentication flows, multi-factor authentication requirements, or different access levels.

How to Configure Targeted Login Pages

1. Identify User Groups: First, determine the groups of users you want to target differently. Examples include:
   • Administrators
   • Standard Users
   • External Partners
   • Users from specific locations
2. Choose an Authentication Method: Select the authentication method you’re using. Common options include:
   • Basic HTTP Authentication (simple, but less secure)
   • Form-based Authentication (more flexible)
   • OAuth 2.0 / OpenID Connect (for third-party identity providers)
   • Custom authentication scripts
3. Implement Conditional Logic: This is the core step. You’ll need to modify your login page or authentication server code to check user attributes and apply different logic accordingly.
   • Username-based Targeting: Check the username entered during login against a list of targeted users.

     if (username == "admin") {
       // Redirect to admin login flow
     } else if (username.startsWith("partner_")) {
       // Redirect to partner login flow
     } else {
       // Standard user login flow
     }
     

   • IP Address-based Targeting: Get the user’s IP address and check it against a list of allowed or blocked IPs.

     if (userIpAddress == "192.168.1.10") {
       // Allow access with reduced security
     } else {
       // Standard security measures
     }
     

   • User Agent-based Targeting: Check the user’s browser and operating system.

     if (userAgent.contains("Mobile") ){
      //Redirect to mobile login flow
     } else {
       // Standard desktop login flow
     }
     

   • Database Lookup: Query a database to retrieve user attributes and apply logic based on the results.

     sql = "SELECT role FROM users WHERE username = '" + username + "'";
     result = executeSQL(sql);
     if (result.role == "admin") {
       // Admin login flow
     }
     

4. Configure Different Authentication Flows: Based on the conditional logic, set up different authentication flows for each user group.
   • Multi-Factor Authentication (MFA): Require MFA for administrators but not for standard users.
   • Different Login Forms: Display a simplified login form for external partners.
   • Access Control Lists (ACLs): Grant different levels of access based on user roles.
5. Testing: Thoroughly test the configuration with users from each target group to ensure it works as expected.
   • Test all login scenarios, including successful and failed attempts.
   • Verify that users are redirected to the correct authentication flows.
   • Check that access control lists are enforced correctly.
6. Security Considerations:
   • Input Validation: Always validate user input to prevent injection attacks.
   • Secure Communication: Use HTTPS to encrypt communication between the client and server.
   • Logging and Monitoring: Log all login attempts and monitor for suspicious activity.
   • cyber security best practices: Regularly update your authentication system with the latest security patches.
