Knox Portal Obfuscator by Matt Hills

Knox Portal Obfuscator hides sensitive data on the Samsung Knox admin portal so you can safely share your screen with partners, on calls, or in recordings.

When enabled (Private mode), it automatically masks:
• License keys (KLM…)
• IMEI / MEID numbers
• Device serial numbers
• Email addresses
• Wi-Fi MAC addresses

Masking keeps the first and last segment so values stay recognizable without exposing the full data — e.g. KLM12-IDL5C-…-9148S becomes KLM12-*---***-9148S.

Click the toolbar icon to toggle between Private (green lock — values masked) and Show (red lock — real values visible). To copy a real value at any time, hover it and click the COPY pill — clicking the value itself still follows its link.

Choose exactly which data types are masked in the options page.

Everything runs locally in your browser. No data is collected, stored off-device, or sent anywhere. The extension only runs on samsungknox.com.
