# Single Sign-On [SSO]
SSO is a user authentication process that allows a user to access multiple applications with one set of login credentials. If your organisation already uses SSO for other applications, Speckle now supports it as well.
# Why SSO?
SSO is a more secure way to manage user access across multiple applications. It enables centralised management of user access and simplifies the process of adding and removing users from your organisation.
# SSO for Workspaces
SSO is available for Workspaces Plus and Workspaces Business plans, ensuring that only users with the correct credentials can access your organisation’s Speckle data.
