# Master Tags
The “Master Tags Security” allows administrators to control user access and the widget's presence on the Home Page.
* **Grant Permissions:** Administrators can define who can use master tags, allowing or denying access for specific user roles or individuals.
* **Set User Permissions:** Grant granular access to various functionalities. For example, editors can add tags but not delete them. Permissions can also be modified or revoked.
* **Configure Widget Visibility:** Administrators can choose whether the master tags widget appears on the homepage or during onboarding, making it easy for users to discover the system.
**Master Tags Permissions (SGA & OE\_ADMIN only)**

* **Grant/Deny Access:** Control which users or roles can view or edit master tags.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.ovaledge.com/release8.3/administration/security/master-tags.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
