### About The Extension

Sensitive Data lets your clients send passwords and other private details with a support ticket, without pasting them into the ticket message.

- The client writes the details in a separate **Sensitive Data** tab when opening or viewing a ticket.
- The details are stored encrypted. They never appear in the ticket message, ticket emails or the WHMCS activity log.
- Only staff members you allow can see the details, and every view and copy is logged.
- Each ticket has one entry.

### Product Requirements

- Phox Templates module **2.4.5** or later
- Phox WHMCS theme active on your client area
- WHMCS **9.0.8** or later
- PHP **8.2** or later, with the **sodium** extension enabled
- An active licence for the Sensitive Data extension
