There are two pieces typically with SAAS apps (that may or may not be applicable to static pages): authorisation and authentication. In most cases, I see B2B offerings supporting SAML + SCIM which helps cover the authentication (AuthN) and authorization (AuthZ) pieces of the puzzle. Or you use oAuth. Most SAAS products also need to map users to what they can do within the app so they need the concept of roles, permissions, etc. It can get quite complex, quite quickly. Something you typically don't need with single user accounts.
