Urblauna access and data transfer
Connecting to Urblauna
The Urblauna cluster is intended for the processing of sensitive data and as such comes with a number of restrictions.
All access requires the use of two factor authentication and outside of the UNIL/CHUV networks the UNIL VPN is required.
Note for CHUV users: in case of problems connecting to Urblauna please contact your local IT team to ensure that the network connection is authorised.
2 Factor authentication
When your account is activated on urblauna you will receive an email from email@example.com that contains a link to the QR code to set up the 2 factor authentication.
To import the QR code you first need to install an application on your phone such as Google Authenticator or FreeOTP+. Alternatively desktop applications such as KeePassXC can also be used.
If you lose the secret then please contact us in order to generate a new one.
