Who will be required to change their password?
Anyone who has not changed their UT EID password since November 2015 will need to change their password. If you are required to change your password, you will receive an email notification from the Information Security Office (ISO) in advance. If you are not sure if you have changed your password in the last three years, we recommend that you change your password now.
When will the password change campaign take place?
Current Faculty will begin receiving notifications on April 1st, followed by a second notice on 4/9. Current Faculty will be required to change their password by April 23rd, 2019.
