Password Guidelines

Your password is the first line of protection for your accounts. It not only protects your email and stored files from being accessed by others, but also prevents others from sending email in your name. Do not give your passwords to anyone and do not write them down in a place others could find.

Trinity students and employees have at least two passwords - one for logging onto the TU Network (LDAP) and one for Tmail. Trinity strongly encourages all users to set up 2-Step Verification for all Google accounts (Tmail, Drive, Calendar, etc.).

Password Guidelines

Your password prevents other people from reading your email, accessing your files, or sending messages from your account. It is against Texas state law to use another person's password to break into their device or account.

While no password is 100% secure, there are steps you can take to make your password as hard to crack as possible. Follow this guide to create a strong password:

Other Tips

  • Change each password (particularly for important accounts) regularly
  • Never use the same user name and password for more than one account - if one password is hacked it won't jeopardize any other accounts
  • Hackers already know the most common tricks - a name backward, using a phone number, zip code, or other personal numbers, and substituting in characters (0 = O, $ = S, % = oo, 8 = B)
  • Use the whole keyboard so if someone is looking over your shoulder as you type they will have a difficult time following the strokes of both hands

Long, cryptic passwords are the most secure but they can be very difficult to remember without the use of a password manager. Instead, start with a short sentence you already have memorized, like a phrase or song lyric, and take the first letter of each word to create a gibberish word that can't be found in a dictionary:

"Oh, say, can you see" becomes Oscys

Combine accepted symbols (perhaps the # because it matches the number of characters in your new word) and numbers (O is the 15th letter of the alphabet) to create an extremely strong password:

Oscys#15 or #Oscys15 or Os#15cys

Changing Your TU Network Password

If you enrolled in Trinity Password Reset, you can reset your password at any time by answering the 3 security questions you submitted during enrollment. If you forget your password or have trouble with your password and did not enroll, please contact the HelpDesk at x7409. For your security, the HelpDesk staff can reset passwords remotely but cannot look up your current password.

  1. Go to Trinity Password Reset
  2. Enroll if you have not already done so. This will allow you to reset your password if you forget it. 
  3. Select the Change [password] link. 
  4. Enter your username, then your old password in the Old Password box and the new password in both the New Password and Confirm New Password boxes. Both the new password and confirm password must match exactly. 
  5. The computer will confirm the change has taken place. 

Changing Your Tmail Password

If you wish to change your Tmail password yourself, simply log into your Tmail account, then follow these instructions:

  1. Click on the icon in the upper right
  2. Select Settings > Accounts tab
  3. Click on Google Account Settings and follow the instructions to create a new password (under Signing Into Google)

You can also call the ITS HelpDesk at x7409 and request a Tmail password reset. Once your password is reset you will be prompted to change it to a new, secure password the next time you attempt to log into Tmail.
