Masking

The Masking App lets you hide, redact, or obfuscate information within a Session. It works on the HTML element level and can be targeted by CSS selectors. Elements are masked before they arrive at participants, so the actual element contents are truly never shared.

• Other Session participants will no longer be able to see the DOM element.
• DOM Snapshots taken through the Automation API will not contain masked elements.
• If installed, the Audit Log App will not log the value contained in tho elements (e.g., register form input changes) (input field data is converted to asterisks).
• If installed, the Session Recording App will see the Session as a Session participant and thus no longer record sensitive informatio that has been masked.

Masked Screen Example

Any changes to masked inputs will also not end up in the Audit Log, but will contain additional details that the element is masked.
