Changing Your CAS Password in Light of the Current Cybersecurity Situation
Published: Friday 13.11.2026
Following an assessment of the current security situation, Charles University is taking preventive steps to better protect your university account and access to our information systems. As part of these measures, we are asking you to change your password for the Central Authentication Service (CAS UK). In the coming days, you will receive an email from CAS UK asking you to do so, but there is no need to wait.
