Staff and Faculty: How to update Apple devices (MacOS) after changing or resetting your password – all campuses

It is important to update all your computers and devices after you have changed your USNH password. Although some applications that will prompt you for your new password there are occasions when you are not prompted and, without even knowing it, your device is making multiple failed attempts to connect to the USNH Network using your old password. After multiple unsuccessful attempts, your account will be locked as a security measure, designed to protect your account from unauthorized attempts.

If your AD account is locked, contact the contact the ET&S Help Desk team on your local campus.

1.  Follow these steps to update the password on your University issued Apple/Mac computer:

Follow these steps to update your Macintosh computer:    

  • Update your Mail program
    • Open your Mail program
    • Go to Preferences
    • Go to Accounts and check for any saved password.  Delete the saved password or update it.

​​​​​​​​​​​​​​2.  Remove your USNH Password from your Mac OSX keychain:

  • It is VERY important the you QUIT all running programs on your Mac computer (HINT: Command-Tab will cycle through all running programs.)
  • Go to Finder>Applications, then Utilities>Open Keychain Access
    • The Keychain Access window has a column along the left side which is split into a top (Keychains) and bottom (Category), plus a listing of individual Keychain items on the right-hand side.
    • In the list of keychains, make sure that the LOGIN keychain is selected.  Click once to select it, if needed
    • In the list of Categories, click on PASSWORDS.  You should see a listing of all your saved passwords on the right-hand of the window.
    • In the very top, right of the window go to search box and type out your campus’ domain:
  • You will likely want to DELETE all of your saved USNH passwords (by pressing the DELETE key) so your Mac will prompt you to enter your NEW password when and if you access that resource in the future.
  • You may be prompted for your Mac’s password.
  • Quit the Keychain Access program.

Your Mac OS X Keychain should now have "forgotten" your OLD USNH password and will prompt you to enter your NEW USNH password as needed
