In this article, I will lead you through the steps of crafting a personalized login page with the help of Keycloak. Having extensive experience with Keycloak, I can guarantee that this custom modification will enhance the authentication process for your application.

Why Customize the Login Page?

By default, Keycloak provides a standard login page that may not align with the branding or user experience of your application. Customizing the login page allows you to create a seamless and cohesive user journey. With a custom login page, you can match the color scheme, fonts, and overall design of your application.

Getting Started

To begin customizing the login page, you’ll need to have Keycloak installed and configured in your application. If you haven’t done this already, I recommend referring to the official Keycloak documentation for detailed instructions.

Once Keycloak is set up, follow the steps below:

  1. Create a new HTML file for your custom login page. You can name it anything you like, such as login.html.
  2. Add the necessary HTML structure to the file, including the login form elements such as username and password fields.
  3. Style the login page using CSS to match your application’s branding. You can change the colors, fonts, and layout to align with your design.
  4. Incorporate any additional elements you want to display, such as a logo or a custom message.
  5. Save the file and upload it to your application’s server.

Configuring Keycloak

Now that you have created your custom login page, it’s time to configure Keycloak to use it. Follow these steps:

  1. Open the Keycloak admin console and navigate to your realm.
  2. Select the “Login” tab.
  3. In the “Login Theme” section, choose the option “keycloak” from the drop-down menu. This will allow you to use your custom login page.
  4. Scroll down to the “Login Form” field and enter the path to your custom login page. For example, if you named it login.html and uploaded it to the root of your application, you would enter /login.html.
  5. Save the changes and restart Keycloak to apply the new configuration.

Testing the Custom Login Page

To ensure that your custom login page is working correctly, follow these steps:

  1. Access your application’s login page in a web browser.
  2. You should now see your custom login page with the design and elements you created.
  3. Enter your credentials and submit the form.
  4. If the login is successful, you will be redirected to your application’s designated landing page.

Conclusion

Customizing the login page in Keycloak is a powerful way to enhance the user experience and align it with your application’s branding. By following the steps outlined in this article, you can create a custom login page that reflects the personality and design of your application. Remember to test the login page thoroughly to ensure a seamless user experience.
