Let us learn more about AWS IAM openid connect with the support of our AWS support services at Bobcares.

What is AWS IAM OpenID connect?

It enables us to authenticate and approve access to AWS services using OIDC-compliant identity providers.

OpenID Connect is an open protocol that enables cross-system single sign-on (SSO). It extends the OAuth 2.0 authorisation mechanism with an identity layer.

We can connect external identity providers that support OIDC into the AWS environment using AWS IAM OIDC.

We may use the AWS Management Console, the AWS Command Line Interface, the Tools for Windows PowerShell, or the IAM API to build and administer an IAM OIDC identity provider.

Create an IAM OIDC identity provider using the AWS Management Console

We may build and maintain an IAM OIDC identity provider using the AWS Management Console, the AWS Command Line Interface, the Tools for Windows PowerShell, or the IAM API.

We must construct one or more IAM roles after creating an IAM OIDC identity provider. A role is an AWS identity that does not have its own credentials (unlike a user).

The role enables your organization’s IdP to request temporary AWS security credentials. What federated users may do in AWS is determined by the policies applied to the role.

To create an OpenID Connect (OIDC) identity provider in AWS IAM?

Follow these general steps to build an OpenID Connect (OIDC) identity provider in AWS IAM:

1. Firstly, open the AWS Management Console and navigate to the IAM service.
2. After that, click on “Identity providers” under the “Access management” section in the left navigation pane.
3. To begin the creation process, click the “Create Provider” button.
4. After that, choose “OpenID Connect” as your provider type.
5. Provide the following information:

   a: Provider URL or metadata document: Enter the URL or directly upload the metadata document from the OIDC provider.

   This page offers information regarding the configuration of the provider.

   b: Audience: Enter a value for the audience, which indicates the application or service that will use the OIDC provider.
6. After reviewing the options, click “Next” to begin.
7. Configure the attribute mappings as follows:

   a: Choose the OIDC properties that will include in the identification token.

   b: Map the OIDC provider characteristics to their AWS IAM counterparts. This mapping specifies how the properties in IAM are represented.
8. Finally, click “Next” to go over the parameters, then “Create” to make the OIDC identity provider.

   When the creation procedure is complete, the new OIDC identity provider will be posted on the IAM identity providers page.

Please keep in mind that based on the AWS Management Console version and upgrades, the particular processes and options may vary significantly.

For the most accurate and up-to-date instructions, see the AWS documentation.

We may use the OIDC identity provider to configure access to AWS resources, by defining IAM roles and activating federation with the identity provider, after splitting it.
