Okta : What Is Single Sign-On (SSO)?

Single sign-on (SSO) is a user authentication tool that enables users to securely access multiple applications and services using just one set of credentials. Whether your workday relies on Slack, Asana, Google Workspace, or Zoom, SSO provides you with a pop-up widget or login page with just one password that gives you access to every integrated app. Instead of twelve passwords in a day, SSO securely ensures you only need one.
