The SAP Single Sign-On solution brings simplicity for your end-users by eliminating the need for multiple passwords and user IDs. In addition, you can lower the risks of unsecured login information, reduce help desk calls, and help ensure the confidentiality and security of personal and company data. In order to meet evolving security demands, you can extend your single sign-on solution even further and offer your end-users “mobile single sign-on”. Your mobile users will have only one password to remember, less typing of complicated user IDs and passwords, and more time for actual work!
SAP Single Sign-On 2.0 (since SP4) supports single sign-on from mobile devices, offering both a simple and secure solution for mobile access to your corporate business processes. The solution is based on time-based one-time passwords (TOTP) generated by the SAP Authenticator mobile app. The SAP Authenticator mobile app is available for both iOS and Android, and supports the IETF standard RFC 6238.
