Personal certificates can be used to authenticate access to web applications and to sign and encrypt emails. The TCS signed certificates have the advantage of being accepted by the majority of browsers and applications without the need of additional configuration (certificates of TCS authority are pre-installed).

Charles University students and staff may obtain TCS personal certificate on-line by authenticating using their CAS account, if:

• they have the verified (strong) password, and
• email addresses validated less than half a year ago.
