Masking
Hiding sensitive information from following-participants
By using Surfly's masking features, you can ensure that confidential information remains private during collaborative sessions. Surfly provides two masking features, Element Masking and Field Masking:
Element Masking allows you to hide entire HTML elements from followers by including their CSS selectors in the hide_element_by_selector option. It does not require any alterations to the web-application's code, and as such, it can be employed on third-party websites as well. You can set it up through the Surfly dashboard or the Javascript API.

The surfly-masked CSS class can be used to customize masking, but this will require making simple code changes to your website/application.
For an example implementation of both the default and customized Element Masking, visit our demo page.
Field Masking allows you to conceal specific form fields from following-participants, preventing them from viewing the tab-owner's input. Credit card and password fields are automatically masked by default. You can add the surfly_private attribute to other fields containing sensitive information, but this will require making simple code changes to your website/application.
<span>Email address</span>
<input type="text" size="20" surfly_private>
Please note that there is an exception to field masking when masked elements/fields are present in an HTML form with method="get" or if the field's value is used in the URL. In such cases, although the fields are masked and not visible to followers in the user interface, the values entered in those fields can still be tracked through Audit Logs (relocate_start event) and may be exposed through browser network activity.
