User authentication and single sign-on (SSO) is an element of your security policies that you can use to protect access to your system infrastructure by securely establishing and propagating the identity of a sender of an access request.

  • User authentication includes the process of securely establishing the identity of a user as a client requesting access to a server system.
  • Single Sign-On (SSO) complements user authentication and includes the process of authenticating an access request once and transparently propagating the identity of an already authenticated user for access to multiple back-end systems.

SAP NetWeaver supports a number of mechanisms to enable user authentication and integration in SSO. For more information about the conceptual, administrative, and development aspects relevant to user authentication and SSO in SAP NetWeaver, see SAP Help Portal: User Authentication and Single Sign-On.

For authentication and single sign-on SAP offers the following two products:

SAP Single Sign-On provides a simple and secure access to IT applications for business users, encrypts company data and provides optionally advanced security to protect important business applications.

SAP Cloud Platform Identity Authentication service provides a simple and secure access to IT applications and is delivered as a service (SaaS, software-as-a-service) by SAP.
