[Faeez]

I am trying to link a embed code in sharepoint site and to approve the domain i wanted to enable the domain from HTML field security option by adding that. unable to find it 

Kindly suggest how do we enable that option to approve my domain using HTML field security

@Faeez you have to be a site collection administrator to see the Site Collection Administration section and the HTML Field Security which is in it.

@RobElliott Thanks for your response! I am part of Site collection administrator but still i do not see that option

@Faeez if you are a Site Collection Administrator then you will see the option to display who are site collection administrators in the top right and you will have the Site Collection Administration menu in the bottom right which includes HTML Field Security.
