Multi-factor authentication will be deployed at the University of Vaasa Open University during spring 2024. This means that all services used by open university students (e.g. Moodle, Peppi and library Tritonia services) will require in the future, in addition to HAKA log-in, to verify log-in either with a Microsoft Authenticator application installed on their own mobile device or with a number code received as a text message. This makes it possible to reliably identify the users of the university's services and to better prevent phishing and misuse of user accounts.
