Accessing the Student Information System (SIS) at Rensselaer Polytechnic Institute (RPI) is a fundamental task for every student, faculty member, and staff member. Often referred to as the "Banner" system due to the underlying software it uses, SIS is the central hub for academic records, financial information, and administrative tasks. To ensure you can log in without friction, you must navigate a specific sequence involving your RPI computing credentials and multi-factor authentication.

The primary gateway for this portal is found at the official address: https://sis.rpi.edu.

Direct Login Requirements for RPI SIS

To log in to the RPI SIS portal successfully, you must have two primary components ready. First is your RCS UserID (Rensselaer Computing System ID), which is distinct from your numeric Identification Number (RIN). Second is the Duo Mobile application configured on your smartphone for Multi-Factor Authentication (MFA).

Most users should follow these steps for immediate access:

  1. Navigate to the SIS login page.
  2. Select the "Login" or "Login to SIS" link.
  3. Enter your RCS UserID (typically a combination of your last name and first initial, e.g., "smithj5").
  4. Enter your associated RCS password.
  5. Complete the Duo Push notification on your registered mobile device.

For those who are accessing the system for the first time—particularly incoming freshmen or new employees—the process may involve an initial setup phase using a RIN and a temporary PIN, but the standard daily login is strictly handled via RCS credentials.

Distinguishing Between RCS ID and RIN

One of the most common points of confusion for members of the Rensselaer community is the difference between the RCS ID and the RIN. Using the wrong identifier is the leading cause of failed login attempts.

What is the RCS ID?

Your RCS UserID is your primary digital identity at Rensselaer. It is used for your RPI email address (e.g., smithj5@rpi.edu), logging into the LMS (Learning Management System), accessing campus Wi-Fi, and signing into SIS. This ID is assigned shortly after your deposit is processed or your employment begins. It usually follows a format of the first five letters of your last name followed by your first initial and sometimes a digit.

What is the RIN?

The RIN (Rensselaer Identification Number) is a nine-digit numerical code, usually beginning with "66". This is your permanent institutional ID. While you use your RIN for physical paperwork, identifying yourself to the Registrar’s office, or picking up your ID card, it is generally NOT used for the main SIS login page once your RCS account is active.

When to use the RIN for Login

The only common scenario where a RIN is used for SIS login is during the very first system entry for new students who have not yet activated their RCS account. In this specific case, the "UserID" field takes the 9-digit RIN, and the "PIN" field takes the date of birth in the format MMDDYY. However, as soon as the RCS account is provisioned, this method is typically deprecated for the more secure RCS/Duo login path.

Implementing Duo Multi-Factor Authentication

Since 2019, RPI has mandated the use of Duo Mobile to protect sensitive student and financial data within the SIS. You cannot bypass this step.

Setting Up Duo Mobile

If you are a new user, you must register your device through the DotCIO (Division of the Chief Information Officer) enrollment portal. Once enrolled, the process of logging into SIS follows this pattern:

  1. After entering your RCS password, the browser will display a Duo prompt.
  2. You can choose "Send Me a Push," "Call Me," or "Enter a Passcode."
  3. The "Push" method is highly recommended. You will receive a notification on your phone; simply tap "Approve."
  4. Once approved, the SIS interface will automatically load.

Troubleshooting Duo Issues

If you lose your phone or replace it with a new one, you will be locked out of SIS. In such cases, you must contact the IT Service and Support Center (VCC Help Desk). They can provide a temporary bypass code once they have verified your identity. It is a good practice to print out "backup codes" from the Duo management portal and keep them in a secure physical location.

Navigating the SIS Interface for Students

Once you have successfully bypassed the login screen, SIS provides several critical modules. Navigating these efficiently is key to managing your academic life at Rensselaer.

Class Registration and Scheduling

Under the "Student Menu," the registration section is the most frequented area. Here, you can:

  • Search for Classes: View the course catalog for upcoming semesters.
  • Register for Classes: Enter CRNs (Course Reference Numbers) during your assigned "time ticket" window.
  • Check Registration Status: See if you have any holds (e.g., medical holds from the Health Center or financial holds from the Bursar) that prevent you from registering.
  • View Weekly Schedule: See a grid view of your current courses and classroom locations.

Financial Records and the Bursar

SIS is the only official way to manage your tuition payments.

  • View eBill: RPI does not send paper bills. You must log in to SIS to see your semester statement.
  • Pay Tuition: SIS connects to the external payment processor where you can set up ACH transfers or credit card payments.
  • Financial Aid: View your aid package, accept or decline loans, and check if there are outstanding documents required by the Financial Aid office.

Academic Records and Transcripts

  • View Grades: Final grades are posted here at the end of each term.
  • Degree Works: This is a vital tool within SIS that tracks your progress toward graduation. It shows which core requirements, HASS (Humanities, Arts, and Social Sciences) depth requirements, and major-specific courses you have completed.
  • Request Transcripts: You can order official electronic or paper transcripts through the SIS interface.

Special Login Procedures for New Students

If you are an incoming student for the fall or spring semester, your SIS login journey begins earlier than your first day of classes.

  1. Post-Deposit Phase: After you pay your enrollment deposit, RPI initiates the creation of your digital identity.
  2. RCS Activation Email: You will receive an email at the address provided in your application with instructions on how to activate your RCS ID.
  3. The First SIS Entry: Before your RCS ID is fully synced with all campus systems (which can take 24-72 hours), you might need to use your RIN and DOB to check your initial financial aid or housing status.
  4. Transition to Standard Login: Once the RCS activation is complete, you should exclusively use the "Login to SIS" button that triggers the RCS/Duo prompt.

Faculty and Staff Access (Rensselaer Self-Service)

For employees, the system is often referred to as Rensselaer Self-Service (RSS). While the login screen looks identical, the menu options differ significantly.

  • Faculty Menu: Used for entering final grades, viewing class rosters, and managing advising profiles for assigned students.
  • Employee Menu: Used for viewing pay stubs, managing tax forms (W-2s), and updating direct deposit information.
  • Time Entry: Hourly employees and student workers use SIS to submit their bi-weekly timesheets for approval.

Troubleshooting Common SIS Login Errors

Despite a robust infrastructure, users frequently encounter errors. Understanding the root cause can save time.

"Invalid Credentials" Error

This is the most frequent error. If you are certain your RCS UserID is correct, try resetting your password through the DotCIO password management site. Note that changing your RCS password updates it for email, Wi-Fi, and SIS simultaneously.

"Account Locked"

Multiple failed login attempts will trigger a security lockout. This lockout usually lasts for 15 to 30 minutes. If the issue persists, the VCC Help Desk must manually unlock the account.

The Duo "Loop"

Sometimes, after approving a Duo push, the browser simply refreshes back to the login screen. This is often caused by corrupted browser cookies or a cache issue.

  • Solution: Clear your browser's cache and cookies for all rpi.edu sites. Alternatively, try using an Incognito or Private browsing window to determine if a browser extension is interfering with the Duo script.

Browser Compatibility

While SIS works on most modern browsers (Chrome, Firefox, Safari), it is built on the Ellucian Banner platform, which occasionally has issues with mobile browsers. If you are struggling to click certain buttons or dropdowns on a phone, switch to a desktop or laptop computer.

Security Best Practices for SIS Users

Because SIS contains your Social Security Number (in some views), financial data, and academic history, security is paramount.

  1. Avoid Bookmark Drift: Do not bookmark the page after you have logged in. The URL contains session tokens that will expire. Always bookmark the base URL: https://sis.rpi.edu.
  2. Logout Completely: When finished, click the "Exit" button in the top right corner and then close your browser tab. Simply closing the tab without clicking "Exit" may leave your session active on public computers.
  3. Phishing Awareness: RPI DotCIO will never ask for your password via email. If you receive an email claiming your "SIS account will be deleted" unless you click a link, it is a phishing attempt. Always navigate to sis.rpi.edu manually.

Technical Support Resources at RPI

If you are unable to resolve login issues independently, the DotCIO provides several avenues for support:

  • The VCC Help Desk: Located in the Voorhees Computing Center, this is the primary physical location for IT support.
  • Online Support Requests: You can submit a ticket via the ITSSC (IT Services and Support Center) portal.
  • Phone Support: The help desk can be reached at (518) 276-7777 during standard business hours.

Frequently Asked Questions

What should I do if I forget my RCS UserID?

Your RCS UserID is typically found in your initial acceptance materials or on your RPI ID card if it was printed after your account was created. If you cannot find it, you must contact the Registrar or the Help Desk with your RIN and a photo ID ready for verification.

Can I access SIS without Duo MFA?

No. Duo MFA is a mandatory security layer for all RPI community members accessing SIS. There are no exceptions for students or faculty.

Why is SIS unavailable on Sunday mornings?

RPI frequently performs system maintenance on Sunday mornings. During these windows, you may see a "System Unavailable" message. Check the DotCIO "System Status" page for scheduled maintenance updates.

Can my parents have their own SIS login?

No. SIS access is governed by FERPA (Family Educational Rights and Privacy Act) regulations. Access is granted only to the student. If you wish to allow your parents to see your bills or grades, you must either show them the screen yourself or set up a "Proxy Access" if that specific feature is enabled for the current term.

How do I update my address in SIS?

Go to the "Personal Information" menu after logging in. You can update your emergency contact info, mailing address, and "Preferred Name" here. It is vital to keep this updated for the RPI Alert emergency notification system.

Summary of the SIS Login Process

Successful access to the RPI Student Information System requires a clear understanding of your credentials and the multi-factor authentication process. By using your RCS UserID and the Duo Mobile app, you can securely manage your academic and financial life at Rensselaer. Remember to always use the official sis.rpi.edu URL and reach out to the DotCIO Help Desk if technical hurdles arise. Whether you are registering for your first semester of classes or checking your final grades before graduation, SIS remains the most critical digital tool in your RPI journey.
