# Tags & Access Control

<figure><img src="/files/zy3WsAgoJ7zk0GfV3tNG" alt=""><figcaption></figcaption></figure>

The **Tags** section allows administrators to control **access permissions** across the platform by assigning tags to users, groups, projects, and sources. This mechanism enables **fine-grained authorization**, making it possible to define who can access what, without hardcoding permissions at the resource level.

Tags act as **permission bridges** between:

* **Who** (users or groups)
* **What** (projects or data sources)

Once a tag is granted, any user or group associated with that tag gains access to the selected resources.

### How to grant access to a project

1. Defines who will receive access. You can grant tags to:
   1. **Groups** (recommended for scalable access control)
   2. Individual users
2. Defines **which resources will be accessible**. Supported sources:
   1. Projects
   2. **Sources** (databases, files, APIs, connectors)
3. Click **Grant** to apply permissions

### Common Use Cases

* Restrict sensitive data sources to specific teams.
* Grant read/write access to analytics projects by department.
* Manage multi-tenant environments with isolated permissions.
* Simplify onboarding by assigning users to pre-configured groups.
