What is Single Sign-On (SSO)?

Single Sign-On (SSO) consolidates the login process from individual systems into a single, separate location - the identity provider. The customer logs in there once and receives a token, and the online store, mobile app, or business dashboard verifies this token instead of asking for a password separately.

In an online store, SSO makes sense when a customer is supposed to have a single account across multiple channels: in the store and the app, in two different stores, or on a B2B platform. We’ve described when it’s worthwhile, how it differs from logging in via Google, and where customer accounts should live in our article Single Sign-On (SSO) in an Online Store.
