# Features and Benefits

## Features

* **Single Sign-On (SSO):** Users can access <code class="expression">space.vars.ionos\_cloud</code> services with their Identity Provider credentials, removing the need for multiple logins. After signing in to an <code class="expression">space.vars.ionos\_cloud</code> account, they can seamlessly use SSO to access other <code class="expression">space.vars.ionos\_cloud</code> services like the **Reseller Portal**, **Control Panel**, and so on.
* **Cross-Domain Collaboration:** IAM Federation, along with SSO, adds cross-domain authentication, allowing users across organizations to authenticate using IDP and access various applications across other organizations without creating new credentials.
* **Standardized Protocols:** IAM Federation supports industry-standard authentication and authorization protocols, such as Security Assertion Markup Language (SAML) and OpenID Connect, ensuring interoperability between different systems and organizations.
* **Security:** IAM Federation provides a secure way to share identities with domain ownership and authenticate users with IDP, reducing the risk of unauthorized access to resources and services.

## Benefits

* **Improved Security:** Identity Provider authentication provides stronger authentication and authorization mechanisms. It also reduces the risk of phishing and password-related attacks.
* **Simplified User Management:** The <code class="expression">space.vars.ionos\_cloud</code> IAM Federation system streamlines user management, allowing contract owners to manage user access to <code class="expression">space.vars.ionos\_cloud</code> services using their existing IDP infrastructure.
* **Enhanced User Experience:** Users can seamlessly access resources without multiple logins.
* **Reduced Administration:** Organizations can reduce the administrative management associated with managing multiple identities and access credentials of users.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ionos.com/cloud/set-up-ionos-cloud/management/identity-access-management/iam-federation/overview/features-benefits.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
