The easiest way to hide form values from Upscope is adding to the input or element the no-upscope class.

Using this method will convert the input value to asterisks, so that the agent can still see the user typing. Upscope would be shown as ******* .

You can also select sections of your webpage through your Upscope dashboard and hide them from view. To do it via your Upscope account, log in, go to General Settings → Advanced →Element Masking.
