2FA protects you

If you are using two-factor authentication (2FA), even if a hacker has your password, your information is probably safe.

Even though there is no evidence that any UD servers have surrendered confidential information as a result of the Heartbleed vulnerability, because this vulnerability could have allowed access to password information for an extended period of time before April 8, the University encourages members of the campus community to change their UDelNet, CAS, email, and other central passwords as soon as possible. All passwords must be changed by April 23.

You can select a new password by logging in to When selecting a new UDelNet password, 

  • Select a password that is 8 to 30 characters in length.
  • Select a password or passphrase that includes at least one character from three of these four categories: Upper case letters, lower case letters, numerals, and any character not listed above (except for a blank space).
