It enables:

- secure connection with encryption,
- use of the same AAI credentials (username + password) everywhere.
✔️ What do I need to use Eduroam?
Valid AAI account (from university or institution).
Official configuration from https://cat.eduroam.org (read instructions SDL.si/en/internet)
Mobile phone or computer with WPA2/WPA3 Enterprise support.
ℹ️ Important
- Always use the official configuration from 👉 https://cat.eduroam.org or https://www.geteduroam.app/
- Do not use old or manually configured profiles 🚫
- If the AAI login does not work, check access to VIS/ŠIS/Moodle – for password issues, contact your faculty.
