Password Standard

The IT department is responsible for the security of sensitive information about students, families, and employees. We maintain network systems that protect computers, encrypt login, and block hacking attempts. If your password is compromised, then hackers gain access to confidential information.

  • Your password must be at least 10 characters in length.
  • You cannot have used this password at Catlin Gabel within the last year.

We suggest inventing a simple phrase that is a few words in length. Adding a number or special character can make your password even more secure. The Upper School attendance system actually requires a number or special character. Please update your password as soon as possible so that you do not lose access to network systems.

How to Change Your Password

Go to Webmail and login to your account. Click on the Gear icon located at the top right-hand corner of the screen:

 

 

At the change password screen enter your old password once and your new password twice. Be sure that your new password is 10 characters long. It cannot be the same as your old password.

Be sure the SAVE your password change by clicking on the SAVE button located above the picture of the keys.

Mac Users

Your computer and network passwords are stored separately. If you want them to match, then change your Mac password in System Preferences.

    

Windows Users

Faculty, staff, and Upper School students may change their network password directly through Windows.

Press Ctrl-Alt-Delete on your keyboard to display the Change Password option. Be sure to do this while ON CAMPUS.

Upper School Attendance

The Upper School attendance system stores your password separately. Please visit the attendance system and update your password there as well.

Security experts vigorously debate the best way to ensure password security. We are siding with length over complexity for the following reasons.

Keeping all other factors equal, longer passwords are harder to crack.

People don't tend to use true complexity.

94 characters are available on the typical keyboard, but people use only 34 of them on average. Complex passwords are rarely actually random.

Password policy is an exercise in keeping ahead of the hackers.

Entropy calculations are based on character length. Counting words instead of characters makes passphrases less attractive. As hackers make the transition to brute force word attacks, the Catlin Gabel password standard may need to change as well.
