SeKA is an acronym, it stands for Semmelweis University Central Authentication (in Hungarian). This system enables our users to access a number of computer services with a single login name and password in a secure way. Another advantage of this system is single sign-on (SSO). This means that if you logged in into any of the services that supports SeKA authentication, you can access all the others without having to type in your credentials again.
You can use your SeKA account to access sites that need EduID authentication (see eduid.hu).
