What does SSO stand for?
SSO stands for single sign-on. It describes a setup in which a person signs in once, through their organisation's identity provider, and is then able to open other approved applications without entering a separate username and password for each. The identity provider is the system that holds the user directory, such as Microsoft Entra ID, Okta, or Google Workspace. Each connected application trusts the identity provider's confirmation instead of running its own login. SSO is mainly a security and administration measure. It reduces the number of passwords in use, applies one set of sign-in rules everywhere, and gives IT a single place to grant and remove access.
