Single Sign-On

SSO

One login that grants access to multiple connected systems.

Single sign-on (SSO) lets a staff user log in once and access multiple connected systems (PMS, channel manager, guest-journey platform, payment gateway) without separate credentials. SSO is increasingly expected at independent properties as the tech stack expands; the SAML or OIDC standards underpin most modern implementations. Properties without SSO accumulate operational friction proportional to stack size.
