Central Authentication Service

About this pageshow/hide

CAS - Central Authentication Service - allows you to access internet services and IT systems of UKSW that require user authentication - using single account stored in USOS (university management system).

While accessing one of our compatible services, you will get redirected to CAS login website:


and after singing in, you will get access at once to all internet services compatible with CAS.

CAS makes your life easier and strengthens your security:

  • by providing you with a single, familiar interface
  • by not requiring you to set up separate accounts in all different services and to remember different passwords - one CAS account allows you to access all compatible internet services, as well as to other services available in the UKSW network and on university premises

Security basics in CASshow/hide

While using Central Authentication System, you must never forget, that:

  • the CAS website should always look the same, any change in the website usual appearance should be a cause of strengthened alert and caution
  • website address must always begin with https://login.uksw.edu.pl
  • website connection must be encrypted, as evidenced by https:// prefix in website address
  • website connection must always be secure, as evidenced by a padlock icon in address bar - always pay attention on that icon, if the website security is endangered, your internet browser will use the address bar and the padlock to warn you (ie. by displaying crossed-over or red padlock)

If you see your logon form displayed on a website that does not conform to above rules, it may be a sign that someone did set up a rouge service

  • For students, attendees etc.:
    • activated from the date of entry into the USOS
    • expires on the last day ending the current studies program (ext. by grace period), please note that for students it is always the ending day of the last unsettled academic year
