How to obtain your network login username and password (students)

Student Username & Password


You will need a username and password to use services on the Trinity network. This is known as your network login username and password.

All users of the Trinity network are bound by Trinity’s IT & Network code of conduct. The main thing to remember is that you must never give your login details to anyone else - as you are responsible for actions carried out under your login.

Obtaining your username & password

Once you complete online registration at my.tcd.ie, you will get a unique Trinity username, and an initial password.

  • Check your intray messages at my.tcd.ie after you have completed online registration for a message with the subject ‘Your Trinity Computer Account’. If you cannot see this message, please click the ‘All Messages’ link.

You will need this username to check your email, gain access to Trinity Wi-Fi, use the Library services online and more, for a listing of services you can access with your username and password see our getting started pages

For security, your initial password must be changed within 14 days of your first login to a computer in Trinity. Please see instructions below on how to do this. If you do not set your own password you will receive an email from IT Services advising you of this password expiry and how to proceed.

Setting your own password

The in-tray message received at my.tcd.ie provides instructions on setting your network login password.

  1. You can do this by visiting http://mypassword.tcd.ie and clicking the ‘Set Password’ link.
  2. You’ll then enter your username and initial password, before being brought to a new web page where you can enter and verify a new password of your choice.

By following these instructions, you will be setting your password for a range of IT systems in Trinity which you will need access to, including your password for MyZone, the student email service. You won’t be able to access MyZone until you have set your own password.

Returning students

Any registered student can collect a printout of their username and initial network login password during standard opening hours from the IT Service Desk by presenting their Trinity ID card.

  • You may wait 4 hours and your account will be unlocked automatically
