+# Enterprise SSO Authentication
+
+Netdata provides you with means to streamline and control how your team connects and authenticates to Netdata Cloud. We provide
+ diferent Single Sign-On (SSO) integrations that allow you to connect with the tool that your organization is using to manage your 
+ user accounts.
+
+ > ❗ This feature focus is on the Authentication flow, it doesn't support the Authorization with managing Users and Roles.
+
+
+## How to set it up?
+
+If you want to setup your Netdata Space to allow user Authentication through an Enterprise SSO tool you need to:
+* Confirm the integration to the tool you want is available ([Authentication integations](tbd))
+* Have a Netdata Cloud account
+* Have Access to the Space as an administrator
+* Your Space needs to be on the Business plan or higher
+
+Once you ensure the above prerequisites you need to:
+1. Click on the Space settings cog (located above your profile icon)
+2. Click on the Authentication tab
+3. Select the card for the integration you are looking for, click on Configure
+4. Fill the required attributes need to establish the integration with the tool
+
+
+## How to authenticate to Netdata?
+
+### From Netdata Sign-up page
+
+If you're starting your flow from Netdata sign-in page you need to:
+1. Click on the link `Sign-in with an Enterprise Signle Sign-On (SSO)`
+2. Enter your email address 
+3. Go to your mailbox and check the `Sign In to Nedata` email that you have received
+4. Click on the **Sign In** button
+
+Note: If you're not authenticated on the Enterprise SSO tool you'll be prompted to authenticate there
+first before being allowed to proceed to Netdata Cloud.
