Frequently Asked Questions

How do I sign in?

The UofSC Central Authentication Service supports the use of three login credentials: Network Username, VIP ID, or Blackboard Auxiliary ID. Enter the appropriate credential and the corresponding password in the form on the Login tab.

The VIP ID is an eight digit number. Faculty and staff were provided their VIP ID after beginning employment. Students were provided their VIP IDs in their acceptance letters and were provided it if they applied for financial aid. You can lookup your VIP ID at https://my.sc.edu/vipid. Select the second link, "I can't remember by VIP ID."

The Network Username is a combination of letters and digits derived from your name; it is assigned by the university. It is also the first part of your official university email address (@mailbox.sc.edu or @email.sc.edu).

The Blackboard Auxiliary ID is used by individuals who need Blackboard access but who do not have a VIP ID or Network Username. This ID is assigned by the Teaching and Technology Services department.

Who must use the VIP ID to sign-on?

Applicants for admission or new students who have not been through orientation must use their VIP ID.

Where do I find my VIP ID?

If you do not know your VIP ID, you can find it here. Select the second link, "I can't remember my VIP ID."

How do I set the password for my VIP ID?

If you know your VIP ID, you can claim your account by establishing a password and setting security questions here.

I've forgotten my VIP ID password. How can I reset it?

  1. Go to the Account Claiming page.

  4. On the next page, enter the answers to the security questions given when you first claimed your account.
  5. After you submit the correct answers to those questions, you will then be prompted to change your VIP ID password.

I've forgotten the password to my Network Username. How can I reset it?

  1. Go to the View my IDs and manage my passwords page.
  2. Use your VIP ID to log into CAS and approve the multifactor authentication.

I don't have the Duo device I registered with me at the moment. How do I get a temporary Duo authorization code?

  1. You can get a temporary Duo authorization code by using the hyperlink Generate Temporary Duo Passcode.
  2. Use your VIP ID for the CAS authentication; a multifactor approval will not be required.
  3. With both the VIP ID and temporary Duo passcode, you can now use the "View my IDs and manage my passwords" page in my.sc.edu to reset the password to your Network Username.

Who can use the Network Username to sign-on?

Only regularly admitted students, faculty, staff, and affiliates can use the Network Username.

How long will I stay authenticated?

Until you close your browser or your session expires, whichever comes first. For your security, it's recommended that you completely close your browser when finished using any web application.

What is CAS?

CAS is a single sign-on process that requires users to provide their credentials once, even if they're trying to access multiple sites or applications, such as Self Service Carolina, my.sc.edu, and other commonly used information systems.

Frequently Asked Questions about DUO Multifactor Authentication

What is Multifactor Authentication?

Multifactor Authentication is a process that supplies additional evidence that your primary credentials are being used legitimately.

Your Network Username or VIP ID are primary credentials -- they are examples of the first factor in authentication. If hackers steal your password or try to guess it through repeated attempts to log-in, the second factor comes from a second interaction with you, via a DUO-enabled device, a telephone call, or text message. You can tell someone, or something, is trying to use your credentials -- because it's not you! When you deny or disapprove a second factor request, the authentication system rejects the login attempt entirely.

How do I set-up two-factor (DUO) authentication?

The process for setting up multifactor authentication for your Network Username is described in the Account Claiming section of my.sc.edu;

The University information security site has information explaining the DUO system and guidance for setting up your DUO device.

What if I don't have a Network Username?

Some university systems require MFA, which is associated with your Network Username. You can not access those systems without MFA. New students only have a VIP ID until they complete the New Student checklist as part of the admissions process. All systems needed to complete the admissions process can be used with the VIP ID without MFA. Once the admissions process has been completed, a Network Username will be assigned and MFA for it can be established.

Former students who attended the university before 2013 may have had a Network Username in the past but it may be have been deactivated because it was not being used. You will need to contact the Service Desk to have your Network Username reactivated.

I only want to order a transcript -- do I need MFA?

Former students and alumni who attended the University before 2013 should contact the Registrar to order transcripts.
