Retool Create Login Page

Web Development Software

Retool is a powerful tool that allows you to build internal tools and applications with ease. One of the essential features of any application is a login page, which ensures secure access to your tool. In this article, I will guide you through the process of creating a login page using Retool and share some personal insights along the way.

The Importance of a Login Page

A login page serves as the gateway for users to access your application. It not only provides a secure entry point but also allows you to authenticate and authorize users based on their credentials.

Before we dive into the technical details, let me share a personal anecdote. When I first started building internal tools for my team, I underestimated the importance of a well-designed login page. I thought it was just a form to collect username and password. However, I soon realized that a user-friendly login page can significantly impact the overall user experience and adoption of the tool.

Now that we understand the significance of a login page, let’s explore how Retool makes it a breeze to create one.

Creating a Login Page with Retool

Retool provides a user-friendly drag-and-drop interface that allows you to build the login page visually. You can add input fields for username and password, along with a “Login” button.

Additionally, Retool provides a powerful feature called “Query Variables,” which allows you to securely pass sensitive data such as passwords without exposing them directly in the code. This ensures that your login page remains secure and protected.

Here’s an example of code snippet using Retool’s query variables:

const loginQuery = {"query": "mutation ($username: String!, $password: String!) { login(username: $username, password: $password) }"};
const variables = {"username": user_input, "password": password_input};

const response = await fetch('/api/login', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
body: JSON.stringify({query: loginQuery, variables: variables})

With the above code snippet, you can securely send the user’s input to your backend API for authentication and retrieve the response.

Adding Personal Touches

Now that you have the basic structure of the login page set up, it’s time to add some personal touches to make it unique to your application.

One way to do this is by customizing the design and layout of the login page. Retool provides a wide range of design options, including themes, color schemes, and custom branding. By aligning the login page with your company’s brand identity, you can create a seamless and cohesive user experience.

Furthermore, you can enhance the login page by adding additional features such as password reset, two-factor authentication, or social login options. These additional features not only improve the security of your application but also provide convenience and flexibility for your users.


Creating a login page is a fundamental step in building a secure and user-friendly application. Retool simplifies this process by providing a visual interface and powerful features like query variables.

By personalizing the design and adding extra functionalities, you can create a login page that reflects your brand and enhances the user experience.
