Eduroam security update – action required

November 11th, 2021

As part of ongoing efforts to maintain a secure wireless network for our users, an update is required to the eduroam wireless certificates. The update will take place from 8am, Friday 26 November 2021.

Following the update, all eduroam users will see a warning on each of their devices that their connection “may not be secure”.

You will be prompted to log-in to eduroam again to accept the new certificate and ensure a secure internet connection via eduroam.

From Friday 26 November, users will need to do any of these steps:

  1. Accept the new certificate when prompted – confirmation of certificate details will be updated on the Digital and Technology Services website on the day
  2. Re-connect using the eduroam Configuration Assistance Tool (CAT)
  3. Failing that, forget the eduroam wireless network and re-connect – instructions on how to connect can be found on the DTS website

Reminder – for eduroam, your username is your university email address. For example:

  • Undergraduate and Postgraduate Taught students: ‘’
  • Postgraduate Researchers, Staff and Associates*: ‘’
  • *Associates without a university email address should use: ‘’

University-managed Windows laptops should automatically apply the new settings on the first reboot after this date, but will require entering your university email address to re-connect.

Although you may be able to connect to the eduroam wireless network without validating the server certificate, your connection will not be secure and your data may be at risk.

If you have any questions, or require any support after the certificate update, please contact our Smart Bar service or IT Service Desk team.
