# Single Sign-On (SSO)

## Overview

**Single Sign-On (SSO)** allows users to securely access **E2E Cloud** and other **organizational systems** using a single set of credentials — managed by a trusted external **Identity Provider (IdP)**.

E2E Cloud currently supports integration with **Microsoft Entra ID**, with support for additional IdPs to be added in future releases to accommodate a wider range of enterprise identity platforms.

This centralized authentication approach simplifies user access across systems, enhances security, and ensures alignment with organizational access control policies.

## SSO with SAML 2.0

E2E Cloud supports SSO integration based on the **SAML 2.0 (Security Assertion Markup Language)** standard — a widely adopted protocol for secure enterprise authentication.

### How It Works

**1. Administrator Setup**  
The organization’s administrator configures **SSO integration** between the **Identity Provider (IdP)** and **E2E Cloud**.  
This setup typically involves exchanging **metadata**, **certificates**, and **redirect URLs** as per **SAML protocols**.

**2. User Invitation**  
Once SSO is configured, the administrator **invites users** belonging to the organization.  
These invited users are then **associated with the organization** within **E2E Cloud**.

**3. User Access Attempt**  
An invited user attempts to **access an E2E Cloud application** that supports SSO using their **Organization ID**.

**4. Redirection to IdP**  
The application **redirects the user** to the organization’s configured **Identity Provider** (e.g., **Microsoft Entra ID**) for authentication.

**5. Authentication by IdP**  
The **IdP verifies the user’s credentials** and confirms that the account exists within the organization’s directory.

**6. Assertion and Access**  
Upon successful verification, the IdP sends a **secure authentication response** back to **E2E Cloud**, granting the user **access to the requested application** without requiring separate credentials.

## Summary

**Single Sign-On (SSO)** simplifies **identity and access management** while strengthening an organization’s overall **security** and **compliance** posture.  
It enables users to **log in seamlessly and securely** across **E2E Cloud services** using a **single organizational identity**.

Next, you can **add and configure an Identity Provider (IdP)** for your organization in **E2E Cloud**.
