For our new friends:

Logto is an Auth0 alternative designed for modern apps and SaaS products. It offers both Cloud and Open-source services to help you quickly launch your identity and management (IAM) system. Enjoy authentication, authorization, and multi-tenant management all in one.

We recommend starting with a free development tenant on Logto Cloud. This allows you to explore all the features easily.

In this article, we will go through the steps to quickly build the Tencent sign-in experience (user authentication) with WordPress plugin and Logto.

Prerequisites

Create an application in Logto​

Logto is based on OpenID Connect (OIDC) authentication and OAuth 2.0 authorization. It supports federated identity management across multiple applications, commonly called Single Sign-On (SSO).

To create your Traditional web application, simply follow these steps:

  1. Open the Logto Console. In the "Get started" section, click the "View all" link to open the application frameworks list. Alternatively, you can navigate to Logto Console > Applications, and click the "Create application" button. Get started
  2. In the opening modal, click the "Traditional web" section or filter all the available "Traditional web" frameworks using the quick filter checkboxes on the left. Click the "WordPress" framework card to start creating your application. Frameworks
  3. Enter the application name, e.g., "Bookstore," and click "Create application".

🎉 Ta-da! You just created your first application in Logto. You'll see a congrats page which includes a detailed integration guide. Follow the guide to see what the experience will be in your application.

Integrate WordPress with Logto​

Install the plugin​

  1. Go to Plugins > Add New.
  2. Search for "Logto", or enter https://wordpress.org/plugins/logto/ in the search box.
  3. Click Install Now.
  4. Click Activate.

Configure the plugin​

Now you should be able to see the Logto menu in your WordPress admin panel sidebar. Click Logto > Settings to configure the plugin.

note:

You should have a traditional web application created in Logto Console before configuring the plugin. If you haven't created one, please refer to Integrate Logto into your application for more information.

The minimum configuration to get started for the plugin is:

  • Logto endpoint: The endpoint of your Logto tenant.
  • App ID: The app ID of your Logto application.
  • App secret: One of the valid app secrets of your Logto application.

All values can be found on the application details page in Logto Console.

After filling in the values, click Save Changes (scroll down to the bottom of the page if you can't find the button).

Configure redirect URI​

The redirect URI is the URL to which Logto will redirect users after they have authenticated; and the post sign-out redirect URI is the URL to which Logto will redirect users after they have logged out.

Here's a non-normative sequence diagram to illustrate the sign-in flow:

Here's how the sign-out flow looks like in a non-normative sequence diagram:

To learn more about why redirect is needed, see Sign-in experience explained.

In our case, we need to configure both redirect URIs in your Logto Console. To find the redirect URI, go to the Logto > Settings page in your WordPress admin panel. You'll see the Redirect URI and Post sign-out redirect URI fields.

  1. Copy the Redirect URI and Post sign-out redirect URI values and paste them into the Redirect URIs and Post sign-out redirect URIs fields in your Logto Console.
  2. Click Save changes in Logto Console.

Checkpoint: Test your WordPress website​

Now you can test your Logto integration in your WordPress website:

  1. Open an incognito browser window if needed.
  2. Visit your WordPress website and click the Log in link if applicable; or directly visit the login page (e.g., https://example.com/wp-login.php).
  3. The page should redirect you to the Logto sign-in page.
  4. Complete the sign-in or sign-up process.
  5. After successful authentication, you should be redirected back to your WordPress website and logged in automatically.
  6. Click the Log out link to log out of your WordPress website.
  7. You should be redirected to the Logto sign-out page, then back to your WordPress website.
  8. You should be logged out of your WordPress website.

Add Tencent connector​

SMS connector is a method used to send one-time passwords (OTPs) for authentication. It enables Phone number verification to support passwordless authentication, including SMS-based registration, sign-in, two-factor authentication (2FA), and account recovery. You can easily connect Tencent as your SMS provider. With the Logto SMS connector, you can set this up in just a few minutes.

To add a SMS connector, simply follow these steps:

  1. Navigate to Console > Connector > Email and SMS connectors.
  2. To add a new SMS connector, click the "Set up" button and select "Tencent".
  3. Review the README documentation for your selected provider.
  4. Complete the configuration fields in the "Parameter Configuration" section.
  5. Customize the SMS template using the JSON editor.
  6. Test your configuration by sending a verification code to your Phone number.

Set up Tencent SMS connector​

Create an Tencent Cloud account​

Go to the Tencent Cloud website and register your account if you don't have one.

Enable and Configure Tencent Cloud SMS​

  1. Sign-in with your account at the Tencent Cloud website and go to the SMS service console page.
  2. Click the “Free Trial” (免费试用) button on the SMS service page and follow the setup steps.

  4. On the “SMS Console Overview” (短信服务控制台概览), choose “Domestic Messages”(国内消息) or “International/Hong Kong, Macao, Taiwan Messages”(国际/港澳台消息) from the sidebar based on your needs.
  5. Add a signature and template for SMS messages. Note:
    • When adding a “Signature” (签名), select “Verification Code” (验证码) under the "Applicable Scenarios" (模版类型) field.
    • When adding a template, choose “Verification Code” as the template type.
    • Include a placeholder {1} in the template content, which will be replaced by a randomly generated code.
    • Templates with multiple placeholders are not supported. Use or create a single-placeholder template.
  6. Submit the signature and template for approval. After submission:
    • Wait for them to take effect.
    • Test SMS can be sent from the “SMS Console Overview” (短信服务控制台概览). Approved signatures and templates can be used directly for testing, or use the testing templates provided if they are still under review.
    • Ensure your account has sufficient balance for testing and pre-register the test phone number to receive SMS successfully.

    • For testing templates, check the “Getting Started” (快速开始) tab under "Test-Exclusive Templates" (测试专用签名模版).
  • Configure the Tencent Cloud SMS Connector with the following fields:
    • accessKeyId and accessKeySecret: Use the credentials from step 1.
    • signName: The signature name obtained in step 2. This applies to all templates.
    • Add multiple templates for different scenarios if needed. Example for a single template:
      • templateCode: Retrieved from the “Template Code” in step 2.
      • usageType: Specify one of Register, SignIn, ForgotPassword, or Generic for different scenarios (Logto-specific property).
      • Ensure templates are configured for all four scenarios to complete the flow.
