Mac Keychain - Remove NMSU item from Keychain Access

Step 1: 

Navigate to the top right corner of your display and click on the Searchlight icon. This action will display a search window; once you see the search bar continue to the next step. 

Step 2:

Type keychain access into the search box and select the first search result directly below the search bar named "Keychain Access". 

Step 3:

This will open your Keychain utility. From here navigate to the search bar, found in the top right of the Keychain Access window, and type NMSU.

Step 4:

The Keychain Access window will now display all keychains linked to NMSU (application) account(s). Select the keychain password that you wish you remove and press the Delete key on your keyboard.

Note: The Keychains displayed will be for NMSU applications and will not affect your password(s) saved through web browser keychains. To delete web browser keychains search for the specific web browser (e.g. Chrome, Firefox, Explorer etc.), select the keychain displayed, and press the Delete key on your keyboard.  

Step 5:

After you hit the "Delete" key the Keychain Utility will prompt you to enter administration credentials before permanently deleting the keychain. 

Note: These credentials will be unique to your computer and are not the same (possibly) as your NMSU credentials. 

Note: If Chrome or another web browser's, keychain(s) is deleted through the process discussed in this document it may delete ALL passwords saved for the browser. If this is not your intention you may choose to delete individual stored password through your browser's advanced settings (in most cases).
