  • Individual files that you create and want to share with other students, faculty, or staff members for comment and/or editing.
  • Files that you create and want to electronically share vs. paper distribution (e.g. notes, agendas, talking points).

Note: College, department, and other group shares will be implemented later this semester in consultation with the various divisions and departments. 

Top Five Features

Box Edit: Box Edit lets users create and edit content directly on myCSUNbox using the native applications installed on their computer. If you can edit it on your desktop, you can edit it on myCSUNBox, all ingrained with how you already work in myCSUNbox. 

Tagging files: Tags allow you to mark and sort related files that may not be located in the same section of your myCSUNbox.

File lock: File lock prevents others from modifying your file if you are working on it. Remember to unlock your file if you want others to edit.

myCSUNbox notification settings: Customize the notices you receive in your email regarding your myCSUNbox account files.

Assigning tasks: Assigning tasks in myCSUNbox notifies an individual and allows users to know to work on specific tasks associated with the files in myCSUNbox.


  • Access myCSUNbox anywhere – save a PowerPoint presentation at home then open it in the classroom, library, coffee shop or conference center.
  • Access myCSUNbox on multiple devices – save files on your laptop and open later on your desktop, tablet or smartphone.
  • Work across platforms – sync a to-do list from a Mac and view it on a PC, iPhone, or Android device.
  • Decide which folders to sync - unlike Dropbox and other personal cloud storage solutions, myCSUNbox lets you decide which folders automatically sync to your devices.

  • Sharing is easy – set up a folder (or file) to share with students, colleagues, committee members, co-authors or other groups.
  • One less thing to forget – become less dependant on using a USB flash drive or portable hard drive.

myCSUNbox can be accessed via the Web from personal computing devices that meet minimum security standards (up-to-date anti-malware software and Operating System patches, require a strong password, and have an Internet Firewall enabled).

Creating a third-party application password

Some applications require a secondary myCSUNbox password be created. This means that the app does not support integration with CSUN's authentication system and requires a separate password set in your myCSUNbox account. For security reasons, do not use your CSUN password as the external password.

To create a secondary myCSUNbox password for use with third-party applications:

  1. In a Web browser, log in to myCSUNbox.
  2. Select the Continue button and log in with your User ID and Password.
  3. Next to your name, select the My Account button (gear icon).

  6. Select the Save button.
  7. Your external password is now set. You can use your CSUN email address and the external password to log in to apps.
