Introduction

• Adding a login system is one of the first steps when building any secure web app, and with Bolt.new, you can do it without writing a single line of code. In this guide, you'll learn exactly how to add a login in Bolt.new using its visual builder, built-in authentication module, and simple workflows. Whether you're creating a startup MVP, client portal, or internal dashboard, this step-by-step tutorial will show you how to build a complete login system that includes user input validation, redirects, third-party OAuth, and best practices for secure access, all inside Bolt.new.

What is Bolt.new and Why Use It for Login Features?

• Bolt.new is a no-code visual development platform that enables you to build web apps with powerful frontends and backend logic, all without writing traditional code. Its intuitive drag-and-drop builder and built-in workflow engine make it an excellent tool for creating login systems with minimal effort.

• Whether you're building a startup MVP or an internal dashboard, secure user authentication is critical. Bolt.new simplifies this process by offering native support for user authentication.

Does Bolt.new Support Login Systems Natively?

• Yes, Bolt.new offers native support for user login, registration, and authentication flows. This is achieved through its Authentication module, which manages user sessions, access control, and integration with external authentication providers, such as Google or GitHub.

• You don’t need third-party tools or custom backend code to set up login Bolt.new handles the infrastructure behind the scenes.

How to Set Up Authentication in Bolt.new (Step-by-Step)

• To set up authentication in Bolt.new, you need to enable its built-in auth module, configure login methods, and connect the login form with backend workflows. Bolt.new simplifies the entire process through its no-code interface, allowing you to implement secure user authentication without writing a single line of code. In the steps below, you'll learn how to enable authentication, design your login UI, and configure the login logic end-to-end.

Step 1: Enable Authentication in Bolt.new

• To begin:

• Go to your Bolt.new Project Dashboard.

• Open the Settings tab.

• Find and enable the Authentication module.

• Choose your preferred authentication methods (email/password, Google, GitHub, etc.).

• This enables login-related workflows and makes user-related data accessible in your logic flows.

Step 2: Designing the Login UI with Bolt.new’s Visual Builder

• Now, create a login screen using Bolt.new's visual builder:

• Drag in Text Input components for email and password.

• Add a Button labelled "Login".

• Optionally include a Checkbox for "Remember Me".

• Customize the UI to match your branding and design system. Bolt's responsive builder ensures it works well on both desktop and mobile.

Step 3: Connecting the Login Form to the Authentication Workflow

• Once your UI is ready, connect it to the backend logic:

• Select the "Login" button.

• In the Actions Panel, trigger a Login Workflow.

• Use the auth.login action with inputs bound to the email and password fields.

• Configure success and error handlers.

• This connects the frontend form to Bolt's backend authentication engine.

Step 4: Adding Redirects After Login (Dashboard/Home)

• You’ll want to redirect users upon successful login:

• In the success handler of the login workflow, use the navigate action.

• Route the user to your dashboard, home screen, or user-specific area.

• You can also pass user data to personalize the destination screen.

Step 5: Handling Errors and Validation for Login

• Proper error handling enhances UX:

• Add conditions for empty input fields.

• Display validation errors like "Email is required" or "Invalid password".

• Use a Text Block to show real-time feedback or errors from the login attempt.

This ensures users are guided through the process smoothly.

How to Add “Forgot Password” and “Signup” Options?

• To build a complete auth flow:

• Create additional screens for Signup and Password Reset.

• Use Bolt’s auth.signup and auth.resetPassword workflows.

• Link to these screens from the login page with text elements (e.g., "Don’t have an account? Sign up").

• These flows can also trigger email verification or password reset links using Bolt’s native features.

How to Test and Preview the Login Functionality?

• Before publishing:

• Use the Preview Mode in Bolt.new to simulate login attempts.

• Test with valid and invalid credentials.

• Confirm that redirects, validations, and UI feedback work as expected.

• Preview on different devices to ensure a responsive login experience.

Can You Integrate with External Auth Providers (OAuth)?

• Yes. Bolt.new supports third-party login via:

• Google

• GitHub

• Facebook (if configured)

• You can enable these in the Authentication settings and include OAuth Buttons in your login screen. This provides a frictionless login experience for users.

Best Practices for Secure Authentication in Bolt.new

• To ensure a secure login:

• Use HTTPS in production.

• Avoid storing passwords in local state; rely on Bolt’s secure storage.

• Use token-based access control for protected routes.

• Set up role-based access to restrict screen visibility.

• Include logout workflows to end sessions securely.

• These measures protect your app and user data.

Final Thoughts: Building a Seamless Login Experience with Bolt.new

• Bolt.new removes much of the complexity traditionally associated with authentication. Its built-in auth module, visual builder, and secure workflows let you create powerful login systems in just minutes.

• Whether you're launching a SaaS product, internal tool, or client portal, Bolt.new ensures a modern, secure, and scalable login experience with zero backend code.
