To access the UniTrento online procedure, identify yourself using the proper credentials:
If, on the other hand, you already have a UniTrento account you are in the wrong place :-)
You cannot register a new account, you need to use the one you already have. If you cannot remember it, use the Retrieve button to obtain the old username and a new password.
Read the data processing disclosure.
For more instructions and to ask for help, consult the UniTrento ServiceDesk portal.
