Encrypted Email and File Sharing

Gmail confidential mode is the recommended email encryption tool for Boise State users. Virtru is also available but limited.

Gmail Confidential Mode

Confidential mode is available on all Boise State Gmail accounts. With Gmail confidential mode, users can send sensitive information as messages and attachments with the extra protection of setting an expiration date and passcode to access the information. Recipients won’t have the option to forward, copy, print, or download the email. Please note this does not prevent recipients from taking screenshots or photos of your message or attachment.

How to Access Gmail Confidential Mode

  1. On your computer, go to Gmail.
  2. Click Compose.
  3. In the bottom right of the window, click Toggle confidential mode.
  4. Set an expiration date and passcode. If you choose “No SMS passcode,” recipients using the Gmail app will be able to open it directly. Recipients who don’t use Gmail will get emailed a passcode. If you choose “SMS passcode,” recipients will get a passcode by text message. Recipient’s phone number is required.
  5. Click Save.
