Introduction to Single Sign-On (SSO)
Table of Contents
Workspace 365/Office 365 administrators are able to enable Single Sign-On(SSO) for their Workspace 365 environment, which helps decreasing login procedures for Workspace users. There are three Single Sign-On options.
- Web Services Federation
- oAuth2 (recommended)
By default there is no Single Sign-On method configured. In this way, Workspace 365 has an own username and password per user.
Web Services Federation
With Web Services Federation (WS-Federation or WS-Fed), you can set up a Federation with an ADFS and/or Azure. In this way the user does not directly sign in to Workspace 365 but via the federation application/server. In most cases this is Azure. This federation is based on the Web Services Federation protocol. For a detailed description about this protocol click here.
OAuth2 is an open standard for authorization, commonly used as a way for internet users to log in to third-party websites using their Microsoft, Google, Facebook, etc. accounts without exposing their password. Generally, oAuth2 provides to clients "secure delegated access" to server resources on behalf of a resource owner.

With configuration of oAuth2 in Workspace 365, you can sign in to Workspace via your current federation and you are able to use MFA, also called 2 Factor Authentication(2FA) or Multi-factor Authentication(MFA).
