Cornell NetIDs

A Network ID (or NetID) is a personal, unique identifier assigned to you. It consists of your initials followed by one or more numbers. You use it, along with a password, to obtain secure access to online services at Cornell.

Activate Your NetID and Email

Beginning October 9, once the university processes your admission response and, if applicable, your deposit, you will receive an email (at your admissions email address) that your NetID was created and what to do next.

Graduate School Students

Cornell Tech (NYC), Johnson MBA, Law, and Vet Students

  • You will receive a text message with instructions to activate your NetID and Cornell email account.
  • If you do not have a text-enabled cell phone number on record, a postal letter with instructions for activation will be mailed to you.

Activate your NetID immediately. As a new student, you will set up your email account when you activate your NetID. Your email address will look something like this——where "ewe1" is your Cornell NetID.


Email service for students at Cornell is provided through Cmail (Google's G Suite for Education). Along with email, Cmail includes calendar, collaboration, and other tools. Learn more about Cmail.

You can choose Cmail and/or provide a valid alternate email address where email sent to your will be directed. This will ensure that you don't miss important university communications.

Regardless of which email option you choose, you can still use the collaboration services offered through Cmail.

Office 365 Email & Calendar

As a graduate or professional student, you have an additional option for your Cornell email—an account on the university's Office 365 system.

Cornell Office 365 accounts for graduate or professional students are intended primarily to be used to perform university business while at Cornell. Guidance about whether a graduate or professional student's work is considered university business should be determined by the department or unit who oversees that work.

For graduate and professional students, Cornell Office 365 accounts provide storage of up to 50GB (gigabytes) and include email, calendar, tasks, and address books.  These accounts are in addition to the Cmail account that every student receives, and/or the email account their department or college may provide.

Get started with your Office 365 account.

Frequently Asked Questions

  • What should I do if I forget my password?

    Passwords are kept in an encrypted database, and cannot be looked up by anyone. If you set up your password's security questions in advance, you can go to the Manage Your NetID web page to set a new password yourself.

    If you forget your NetID password, and you did not set up your password’s security questions, you will need to request a new activation code so that you can reset your password.  To make this request, visit the IT Service Desk in person, or contact them to schedule a video chat. You will need to provide proof of identity—your Cornell ID card or your valid government-issued photo ID card, such as a driver’s license or passport.

  • Is it okay to share my NetID and password with family or friends?

    No. Your NetID is for your exclusive personal use. It is a violation of university policy to share your NetID and passwords with anyone, including friends and family members. If someone has your NetID and password, they can look up and/or change personal and confidential information, violate federal privacy laws through your account, and more. Keeping your NetID password safe is one way you can help protect your personal information and Cornell's data.
