In today's interconnected world, users expect a seamless and secure login experience on websites and applications. Social media provider authentication, such as Google Authentication, offers a convenient and trusted way for users to access your application using their existing social media accounts. In this tutorial, we'll explore how to integrate Google Authentication into your ASP.NET Core application step by step.
Before we dive into the implementation, make sure you have the following:
- Visual Studio or Visual Studio Code installed on your system.
- An ASP.NET Core web application project was created.
Step 1: Install the Required NuGet Package
The first step is to install the
Microsoft.AspNetCore.Authentication.Google NuGet package into your ASP.NET Core project. This package provides the necessary tools for integrating Google Authentication.
Open the NuGet Package Manager in Visual Studio, search for
Microsoft.AspNetCore.Authentication.Google, and install the latest stable version.
Step 2: Configure Google Authentication
To enable Google Authentication in your application, you need to set up the necessary credentials on the Google Developer Console. Follow these steps:
Navigate to the Google Developer Console.
Create a new project or select an existing one.
Set up the consent screen by providing the required information, including the application name, support email, and domain.
Under the "Scopes" section, add the necessary scopes, such as
Save your changes and publish the app.
Create OAuth 2.0 credentials by going to "Credentials" and selecting "Create credentials" > "OAuth client ID." Choose the application type as "Web application" and configure the redirect URIs.
After creating the OAuth client ID, note down the "Client ID" and "Client Secret" values.
Step 3: Configure Your ASP.NET Core Application
Now, let's configure your ASP.NET Core application to use Google Authentication. Open your
appsettings.json file and add the Google Authentication settings:
// Other application settings...
"YOUR_CLIENT_SECRET" with the values you obtained from the Google Developer Console.
Step 4: Enable Google Authentication in Your App
In your ASP.NET Core application, navigate to the
Program.cs file. Inside the
CreateHostBuilder method, add the following code to enable Google Authentication:
options.ClientId = Configuration["Authentication:Google:ClientId"];
options.ClientSecret = Configuration["Authentication:Google:ClientSecret"];
This code configures the authentication services to use Google Authentication and sets the client ID and client secret from your
Step 5: Run Your Application
With Google Authentication configured, you can start your ASP.NET Core application. You should now see the "Use other services to log in" option on your login page, with Google as one of the available choices.
Click the "Google" button, and a popup will appear, prompting you to sign in with your Google account. After signing in, you'll be redirected back to your application, logged in, and authenticated via Google.
Integrating Google Authentication into your ASP.NET Core application provides users with a convenient and secure way to access your services without creating additional accounts. This enhances the user experience and can boost user engagement on your platform.
