Federated Authentication

Follow the instructions given here to try out federated authentication.

Problem scenario

Pickup works with a team of external consultants. However, it is a hassle to keep adding and maintaining their accounts in the employee database as these consultants are temporary and employed on a rolling basis.

Therefore, Pickup decides to use the identity federation capability of MWARE IAM. This allows external consultants to use their existing Google account credentials to sign in to Pickup applications.


Install MWARE IAM and start the server.

Set up a Google OAuth 2.0 application

Follow these instructions to register an OAuth 2.0 application in Google.

  1. Go to the Google Developer console, create a new project or select an existing project.

  2. If the APIs & services page isn't already open, do the following:

    1. Open the navigation menu and click View all products. View all products on the Google console

    2. Under Management, click APIs & Services. Select APIs & Services

  3. Go to the Credentials page, click Create Credentials, and select OAuth client ID.

    Select APIs & Services

  4. Configure your consent screen by clicking Configure Consent Screen and return to Create OAuth client ID screen once you are done.


    For more information, see User Consent

  5. Select Web application as the application type.
