Yes, it is feasible to create a machine-to-machine OAuth client for every user. This can be done using the Client Credentials Grant, which is commonly used in machine-to-machine communications. This allows web services, applications, or devices to call each other without the context of human users. Activity that uses this grant often runs in the background and doesn't require any user interaction. Here are the steps to create an OAuth2 client for machine-to-machine communication using the Ory CLI: 1. Create an Ory Network project and export the project ID:

bash ory create project --name "Ory OAuth2 Example"   project_id="{set to the project ID from output}"

2. Create an OAuth2 client:

bash ory create oauth2-client --project "$PROJECT_ID" \     --name "Client Credentials Demo" \     --grant-type client_credentials

3. Export the ID and secret of the created client:

bash client_id="{set to CLIENT ID from output}"   client_secret="{set to CLIENT SECRET from output}"

4. Start the Client Credentials Grant:

bash ory perform client-credentials \     --client-id="$client_id" \     --client-secret="$client_secret" \     --project "$PROJECT_ID"

5. Perform token introspection to get the

access_token

details:

bash # Export 'access_token'   access_token="{set to ACCESS TOKEN from output}"      # Perform token introspection   ory introspect token $access_token --project "$PROJECT_ID"

It is capable of issuing access, refresh, and ID tokens in a secure and OpenID Certified manner. It can connect to your existing identity management and is suitable for scenarios that involve machine-2-machine interaction.
