Updates and Changes to TAMUS Single Sign-in

All Tarleton faculty, staff, and student workers are required to use their UIN and password to log into Single Sign On. The option to use your Tarleton NTNET account has been removed.

For improved security, Tarleton requires the use of UIN and password logins for all users. This provides the greatest level of account protection for those who use 2-factor authentication.

Using Your UIN

On the homepage of SSO, your UIN is displayed in the top left corner. If you are enrolled with Blue Cross Blue Shield insurance, your nine digit UIN is shown on your insurance card. In addition, your supervisor can look up your UIN using the TAMUS Monthly Payroll BVDS.

UIN Recovery

If you forgot or need to recover your UIN, you can request a one-time use password. This wizard will walk you through the steps of creating a one-time use password, and will send you a temporary password via email at the end of the process. Contact Employee Services with any questions or concerns regarding your UIN.

Duo 2-Factor Authentication

With two-factor authentication, you will protect your SSO login with something you know (e.g. your password) and something you have (e.g. your duo-enrolled device). Verifying your identity using a second factor, such as your phone or other mobile device, will prevent anyone but you from logging in, even if they know your password.

Two-factor authentication adds a second layer of security, keeping your SSO login secure even if your password is compromised. Once you have enrolled, you will be alerted right away via your duo-enrolled device if someone is attempting to log in as you.

 Duo-Enrolled Devices

We strongly recommend using the Duo mobile app for your duo-enrolled device, as it is the most user-friendly option. However, other options are available, including your work phone. View all available options.

If your mobile phone is your duo-enrolled device and you happen to lose it or it is stolen, call Employee Services immediately at 254-968-9128. The administrator will disable it for authentication and assist you in the process if logging into another phone. Remember that your UIN and password will continue to protect your account even if your phone is lost.

You will be able to change your duo-enrolled device to a different phone with a different number. You will need to reactivate Duo on the new device if it’s a different type of device (e.g. moving from an Android phone to an iPhone) then make sure to select the new phone type before reactivating. You can also reactivate Duo on a new device with the same number, and will need to make sure to select the new phone type upon reactivating in this situation as well.

In cases where cell coverage is not available, use the Duo mobile app to generate a passcode, which you will use as your second factor. If you’re not using a smartphone or don’t have access to the app, then generate passcodes in advance.
