Please note that IT Services has no jurisdiction to add/amend access entitlements to Trinity Web Systems applications.


Q. I can’t login to the Trinity Web Systems
A. Confirm that you have registered for Trinity Web Systems using your Trinity username and network login password. If not, then register via the 'Register' button on the main Trinity Web Systems login page.

If you still cannot gain access after registering then make sure you are using the correct username and password i.e. the username for the COLLEGE domain and the network login password for the COLLEGE domain - not the Computer Science domain or any other domain.

If you have confirmed the username and password are correct and still cannot gain access your account may have become 'locked out' due to too many unsuccessful attempts to enter your password. In this case you can unlock your account using TCD Password Manager, if you have signed up for this service, you can wait 4 hours for the account to unlock itself, or you can call in person to the IT Service Desk.

Q. I can login but I can't access the web systems I need?
A. If you have recently changed department or role, the access entitlements accorded to the new role may not yet have been fully processed by Human Resources. In addition, once processed it generally takes another day for your Trinity Web Systems access permissions to become available.

If you still have need of assistance contact the IT Service Desk. They will log a ticket in their system, and contact you in due course.
