# What is single sign-on (SSO)?

Single sign-on (SSO) lets people log in once with one company account and then use many applications without separate passwords for each. A central identity provider checks the login, ideally with multi-factor authentication, and tells each application who the person is, often using a standard called SAML or OpenID Connect. SSO is good for security because there are fewer passwords to steal and leavers lose access everywhere at once when their account is disabled. The flip side is that the central account becomes very valuable, so protect it well. In NetSenX, SSO with SAML is available on the Enterprise plan.
