How To Configure Amazon Cognito for NGINX Plus OIDC Integration

Take the following steps to create a new application of Amazon Cognito for integrating with NGINX Plus.

Note:

The following procedure reflects the Cognito GUI at the time of publication, but the GUI is subject to change. Use this guide as a reference and adapt to the current Cognito GUI as necessary.

Create a new User Pool

  1. Log in to your AWS account, open the AWS Management Console, and navigate to the Cognito dashboard (you can, for example, click Cognito in the Security, Identity, & Compliance section of the Services drop‑down menu).

  2. On the Cognito dashboard, click Manage User Pools to open the Your User Pools window. Click the Create a user pool  button or the highlighted phrase.

  3. Configure sign-in experience as the following example:

  4. Configure security requirements as the following example:

    Note: Select No MFA for your quick testing. Otherwise configure multi-factor authentication.

  5. Configure sign-up experience as the following example:

    Note: select additional required attributes such as preferred_username because it is used for NGINX Dev Portal.

  6. Configure message delivery as the following example:

  7. Integrate your app as the following example:

    Note: You can create your app either in this step or after creating a user pool.

    • Option 1. Check Generate a client secret if you want to disable PKCE

    • Option 2. Check Don't generate a client secret if you want to enable PKCE

  8. Review and create a user pool:

  9. Click Create user pool button:

Create a user

  1. Select a user pool (nginx-oidc-user-pool) that you created:

  2. In the tab of Users, click Create user button:

  3. Add a user name that you want to create:

    Note: Select Don't send an invitation for your quick testing to create dummy email address.

Create a domain

  1. Select a Create Cognito domain in the list after selecting the tab of App Integration:

  2. Type a domain prefix in the Domain prefix field under Cognito domain (in this guide, my-nginx-plus-oidc). Click the Create Cognito domain button:

  3. Check if your domain is created:

Create or Edit a new Application

  1. Select the tab of App Integration in the user pool:

  2. Scroll down from the tab of App integration, and select Create app client button

  3. Enter a name of app (in this guide, nginx-oidc-app for non-PKCE, nginx-odic-app-pkce for PKCE) in the App client name field. Make sure that you choose one of the following options.

    • Option 1. Check Generate a client secret if you want to disable PKCE

    • Option 2. Check Don't generate a client secret if you want to enable PKCE

  4. Find Hosted UI settings after scrolling down, and perform the following steps:

    • 4.1 In the sections of Allowed callback URLs and Allowed sign-out URLs, type the URI of the NGINX Plus instance including the port number, and ending in /_codexch for callback URL and /_logout for sign-out URL as follows.

      • Allowed callback URLs: https://nginx.cognito.test:443/_codexch.
      • Allowed sign-out URLs: https://nginx.cognito.test:443/_logout.

      Notes:

      • For production, we strongly recommend that you use SSL/TLS (port 443).
      • The port number is mandatory even when you’re using the default port for HTTP (80) or HTTPS (443). But it it isn't needed if you use NGINX ACM.

    • 4.2 In the OAuth 2.0 grant types section, click the Authorization code grant checkbox.

    • 4.3 In the OpenID Connect scopes, click the email, openid, and profile checkboxes.

    • 4.4 Click the Save changes button.

  5. Check the App client list in the tab of App integration under the user pool of nginx-oidc-user-pool to see TWO applications (#1 for non-PKCE, #2 for PKCE) are created.

  6. Click one of app clients to note Client ID and Client secret for configuring NGINX Plus.

    • Option 1. Copy and note Client ID and Client secret for non-PKCE application.

    • Option 2. Copy and note only Client ID for PKCE application.
