Yes. The EWP network uses up-to-date security and authentication protocols. EWP is meant for HEI staff, and they log in using their own HEI login. The HEI sets the rights (to the server) itself. So everyone who is given the rights to login to the server connected to the EWP Network, can use EWP. For the technically oriented, an overview of EWP security measures can be found at https://developers.erasmuswithoutpaper.eu/ in chapter 2, more particularly in sections 2.2 - 2.6. Of interest is also https://github.com/erasmus-without-paper/ewp-specs-sec-intro/tree/v2.0.2 where a good and detailed description of the "Authentication and Security" issues can be found.
