Integrating Passkey Authentication in a Next.js App

This repository demonstrates how to add passkey login functionality to your Next.js app using the Hanko Passkey API. Passkey authentication is a secure and user-friendly alternative to traditional password-based authentication, providing a seamless login experience for users.

For a detailed tutorial on implementing passkey login in your Next.js app, refer to our blog post: How to add passkeys to your Next.js Application

Prerequisites

Before you begin, ensure you have the following:

• Node.js installed (version 20.0.0 or later)
• Hanko Passkey API key and tenant ID from Hanko Cloud

Note: You'll need to create a Passkey Project on Hanko Cloud with the App URL http://localhost:3000. See our docs to learn how to setup a passkey project.

Getting started

1. Clone the repository

git clone https://github.com/teamhanko/passkeys-nextjs.git

2. Set up environment variables

   • Create a .env file in the root directory and add the following environment variables:

   PASSKEYS_API_KEY=your-hanko-passkey-api-key
   PASSKEYS_TENANT_ID=your-hanko-passkey-tenant-id

   • Replace your-hanko-passkey-api-key and your-hanko-passkey-tenant-id with your actual Hanko Passkey API key and tenant ID.

3. Install the dependencies using your preferred package manager (e.g., npm, pnpm, yarn, or bun). For this project, we've used pnpm:

pnpm install

4. Start the development server:

pnpm dev

Usage

1. Start the application:

   • Access the application by navigating to http://localhost:3000 in your web browser.

2. Log in with a pre-configured user: Navigate to login page, login with one of the pre-configured users.

    {
        "id": "b3fbbdbd-6bb5-4558-9055-3b54a9469629",
        "email": "[email protected]",
        "password": "password123",
    },
    {
        "id": "22c81b3d-1e7d-4a72-a6b0-ad946e0c0965",
        "email": "[email protected]",
        "password": "very_secure_password",
    },
    {
      "id": "55c81b3d-1e7d-4a72-a6b0-ad946e0c0965",
      "email": "[email protected]",
      "password": "123",
    }

3. Register a passkey:

   • After logging in, register a passkey for the logged-in user.

4. Log out:

   • After the passkey registration is successful, log out of the application.

5. Login with with a passkey

   • On the login page, choose sign in with a passkey option to authenticate using a passkey.
