Windows authentication
Windows authentication is a method available exclusively to customers with on-premise installations of Fusion Online. This option allows users to seamlessly log in to Fusion Online using their existing Active Directory accounts without needing to manually enter credentials.
What is on-premise Fusion Online?
In an on-premise setup, Fusion Online is hosted on your company’s internal servers, which are supported by your IT department. Since the application runs within your company’s network, it can be configured by IT to support Windows authentication, enabling users to automatically connect when logged into their computers with Active Directory credentials.
How Windows authentication works
When configured, the web server hosting Fusion Online will use Windows authentication to automatically authenticate users. As long as your Windows username matches an active Fusion Online account, you will be logged in automatically without seeing a login page.
When your browser connects to the Fusion Online web server, it authenticates you using Windows credentials.
The server checks if your Windows username matches an active Fusion Online account. If it does, you are logged in seamlessly.
If your Windows username does not match an active Fusion Online account, you will be redirected to the standard username/password login screen.
Setting up Windows authentication
The setup and configuration of Windows authentication are described in the Fusion Online Installation Guide, which is provided alongside the installation program for Fusion Online. This process must be handled by your IT team.
Fusion Online user accounts must be specifically set for Windows authentication during the invitation process or later in the User Details.
To enable Windows Authentication, administrators need to ensure the following steps are completed:
The web server is correctly configured for Windows authentication as outlined in the Fusion Online Installation Guide.
Windows authentication is enabled for the entire system through the System Options page once the server configuration is complete.
Invitation process
The invitation process for Windows authentication works similarly to other authentication methods, but with a few differences:
After accepting the invitation, users only need to provide their first and last names. There’s no need to create a username or password since the system uses their Windows username.
Users will be automatically logged in if their Windows username matches an active account.
Switching between accounts
If you have both a Windows authentication account and a username/password account, you can switch between them:
Click on your profile image in the top-right corner of the page to open the menu, then select the Logout action.
On the login screen, use the Windows authentication toggle to switch between your Windows account and your username/password account.
This can be useful if, for example, you have an administrator account that is not tied to your Windows username but also have a personal account that is.


Troubleshooting Windows authentication
If your browser prompts you with a pop-up window asking for a username and password, this indicates that Windows authentication is not configured correctly. This issue could stem from either your computer or how you logged in to it. In such cases:
Contact your IT department to resolve the issue.
When working correctly, you should not be prompted to enter a password when accessing Fusion Online.
