CNet Account and Password/Passphrase FAQ

This article explains answers to frequently asked questions regarding CNet accounts and passwords/passphrases.

Note: If your question is related to account closure, you should examine Account Closure, Eligibility & Information.

CNetID? CNetID Password/Passphrase? What are those for?

Most people have more usernames and passwords than they'd care to remember; to address this problem, IT Services has moved toward a single set of credentials for authenticating against all common services we provide. The result of this is the Chicago Network ID most commonly known as the CNetID and the CNetID password - a single username/password pair to authenticate against as many services as possible. The CNetID password must be at least 12 or more characters in length.

Another option for users of University services (such as the Directory, myUChicago, or UChicago Google Applications) instead of a password is a passphrase. The CNetID passphrase, which uses a phrase meaningful to you that you get to pick, functions identically to a CNetID password by authenticating you for all the common services you are eligible to use based on your affiliation with the University. The CNetID passphrase must be at least 19 or more characters in length.

I was trying to change my password/passphrase but it says my account is locked!

This is generally because you've tried and failed to authenticate a total of ten times. Talk to the Identification and Privileges Office (IPO) to unlock your account. This is a security precaution to prevent someone from trying to break into your account through brute-force guessing.

I forgot my CNet password/passphrase; how can I reset it?

If you've forgotten your CNetID password or passphrase (or even if you haven't), you can change your password or passphrase (see CNetID - Changing Your CNet Password or Passphrase) through the CNet Account Management website. If you are unable to reset it through the CNetID website, you can reset it in person at the Identification and Privileges Office (IPO) in the Regenstein library.

I lost my password/passphrase. Can I recover it?

No, you cannot recover a lost password or passphrase - it was hashed (encrypted) in a non-recoverable form as soon as you created it. This is a security mechanism that helps ensure that your password or passphrase cannot be compromised.

While you can't recover your old password or passphrase, you can change your CNetID password or passphrase (see CNetID - Changing Your CNet Password or Passphrase) if you've lost it (or even if you haven't). If you can't reset your password or passphrase online, contact the Identification and Privileges Office (IPO) at 773-702-8782.

Can I reuse an old CNet password or passphrase?

No, you may never reuse or renew CNet passwords and passphrases . You may, however, create a plan for changing your password or passphrase that allows you to easily remember successive passwords/passphrases. If your passphrase were “Oh, say can you see by the dawn’s early light” changing the passphrase can be as simple as moving on to the next line; “What so proudly we hailed at the twilight’s last gleaming?”

I don't remember my CNetID; can I look it up?

If you have forgotten your CNetID, you may look it up at whoami.uchicago.edu. Alternately, you may contact the Identification & Privileges Office (IPO). They are located in the lobby of the Regenstein Library or you can call (773) 702-3344.

I want to change my CNetID, what do I do?

CNetIDs cannot be changed. If you want to change your CNetID because of harassment, stalking, or other such factors, contact abuse@uchicago.edu to discuss the situation. If you're looking for an alternate email address, you should create an alias (seeCNetID Email Aliases).

My attempt to create an account failed... why?

If you are unable to create a CNetID online through the CNetID Account Management website you may fall under one of the following cases:

  • You aren't in the system yet
  • You have mis-entered information in the system
  • You are not eligible for an account.

To determine which of these is the case, contact the Identification and Privileges Office (IPO).

What's the difference between my @midway and @uchicago email addresses?

For almost all purposes there is no difference between @midway and @uchicago addresses. You should only give out your @uchicago.edu address, as @midway.uchicago.edu addresses are considered deprecated and only maintained as a legacy service.

If I used to be a student, but am now a staff member (or vice versa)...what happens?

While some changes are made to your user account when you switch between student, staff, or faculty status your account name and password are unaffected. In other words, while you may be using different services, you will access them in the same way. You should replace your UChicago ID card when you change roles at the Identification and Privileges Office (IPO).
