How to Register Your CNDA2 Account

Overview

CNDA is migrating to a new system (CNDA2) that uses WashU Key for authentication instead of local usernames and passwords. All users must create a new CNDA2 account. The Cutover date is 7/5/2026.

Right now, we are in the registration phase and the only thing that works is registering. Logging in and seeing things on CNDA2 has not been enabled yet. Do not try to log in after registering.

Before You Start

  • You must have a WashU Key
  • You will create a new account on CNDA2
  • Your existing project access will be re-linked once data migration is complete — we will announce when the system is ready

Step 1: Create Your CNDA2 Account

  1. Go to: https://cnda2.wustl.eduopen in new window

Important

  • Do not enter anything in the USER or PASSWORD fields
  • Do not click Register or Forgot Login
  1. Click WUSTL Connect

The CNDA2 login page. Leave USER and PASSWORD blank and click the WUSTL Connect button.

  1. Log in with your WashU Key
  2. Complete two-factor authentication if prompted

Step 2: Complete Registration

After authenticating, you will be redirected back to the CNDA2 registration page.

The CNDA2 registration page. Select "A New CNDA Account" and replace the generated username with your existing CNDA1 username.

  1. Ensure A New CNDA Account is selected
  2. Replace the generated username with your existing CNDA1 username

Username Requirement

You must enter the username you currently use on CNDA1. If you use a different username, your project access cannot be linked automatically. Your WashU Key is assigned an internal ID that only WashU IT can see — your CNDA1 username is the only identifier we have to connect your new account to your existing projects.

  1. Verify your first and last name are in the correct fields — some browsers autofill them in reverse order, as shown in the screenshot above. Correct manually if needed.
  2. Click Register

Step 3: Wait for Migration Completion

After registering:

  • Do not begin normal work in CNDA2 until the cutover date
  • Wait for the official migration announcement

You will be notified when the system is ready for use. Your project access will be restored automatically at that time — no action is needed on your part except to register for an account.

Notes

  • Your old CNDA account is not transferred until the cutover date
  • Project access will be re-linked automatically based on your CNDA1 username on the cutover date — no need to contact the Help Desk
  • cnda2.wustl.edu is a temporary address used during the migration period. After cutover, CNDA2 will move to its permanent address at cnda.wustl.edu.
  • Scripts and XNAT Desktop Client users will need alias tokens after cutover — see How to Generate and Use Alias Tokensopen in new window
