Cognito Custom Login Page

Web Development Software

As someone who has worked extensively with Amazon Cognito, I understand the importance of customizing the login page to create a seamless and branded user experience. In this article, I will guide you through the process of creating a custom login page using Amazon Cognito. But before we dive into the details, let’s take a moment to understand what Amazon Cognito is and why it’s essential for modern web applications.

Introduction to Amazon Cognito

Amazon Cognito is a fully managed service provided by Amazon Web Services (AWS) that allows you to easily add user sign-up, sign-in, and access control to your web and mobile apps. It provides secure authentication and authorization capabilities, allowing you to focus on building engaging user experiences rather than dealing with the complexities of user management.

Out of the box, Amazon Cognito provides a default login page with basic styling that may not align with your brand identity. Customizing the login page not only enhances the user experience but also helps in establishing trust and credibility with your users.

Creating a Custom Login Page

Customizing the login page in Amazon Cognito involves a few simple steps:

  1. Create an HTML page that defines the structure and styling of your custom login page.
  2. Upload the HTML page to an Amazon S3 bucket or host it on your own server.
  3. Configure your Amazon Cognito user pool to use the custom login page.

Let’s go through each step in detail.

Step 1: Create an HTML Page

To create a custom login page, you need to have a basic understanding of HTML, CSS, and JavaScript. Start by creating an HTML file that defines the structure and styling of your login page. You can use any code editor or even a simple text editor to create the file.

When designing your login page, keep in mind the elements that are required for user sign-in, such as email and password fields. You can also add additional fields, such as a “Remember me” checkbox or a “Forgot password” link, based on your application’s requirements.

Step 2: Upload or Host the HTML Page

Once you have created the HTML file for your custom login page, you need to host it either on an Amazon S3 bucket or on your own server. If you choose to use an S3 bucket, upload the HTML file along with any associated CSS or JavaScript files that are required for the page to function correctly.

If you prefer hosting the HTML file on your own server or another web hosting provider, ensure that the appropriate files are transferred to the server and the necessary permissions are set.

Step 3: Configure your User Pool

The final step is to configure your Amazon Cognito user pool to use the custom login page. Open the Amazon Cognito console and navigate to your user pool. In the “App client settings” section, scroll down to the “App client settings” area and scroll to the “App client settings” area. Under the “App client settings” section, you will find the “App client ID” and “App client secret” fields.

In the “App integration” section, you will find the “Domain name”, “Callback URL”, and “Sign out URL” fields. Enter the URL of your custom login page in the “Callback URL” field and any other necessary URLs in the respective fields.

Save the changes, and your Amazon Cognito user pool is now configured to use the custom login page.


Customizing the login page in Amazon Cognito allows you to create a unified and branded user experience. By following the steps outlined in this article, you can easily create and configure a custom login page that aligns with your application’s design and requirements.

Remember, the login page is often the first interaction users have with your application, so it’s essential to make a positive impression. Take the time to design a visually appealing and user-friendly login page, and you’ll be one step closer to providing a seamless and engaging user experience.
