# MAC Address Restrictions

#### MAC Address Restrictions 

The **MAC Address Restrictions** page in *Skillmine Auth* allows administrators to define, organize, and control access to the system based on **device MAC addresses**.\
This ensures that only registered or authorized devices can connect, adding an additional layer of security and control to your authentication environment.

After implementing MAC Address Restrictions, **Skillmine Auth Browser becomes mandatory** for users to access applications.\
This enforcement ensures that users can only access the application through the **Skillmine Auth Browser**, thereby preventing access from standard or unapproved browsers.\
By doing so, administrators can maintain a **secure and controlled access path** that aligns with organizational security policies.

Administrators can create groups of MAC addresses, associate them with specific teams or use cases, and manage their access permissions centrally. 

This page is used to: 

* Create and manage MAC Address Groups for logical collections of devices categorized by teams, departments, or functions. 
* Add, view, and edit MAC addresses within each group. 
* Restrict or allow access based on specific devices to strengthen endpoint-level security. 

By enforcing MAC-based restrictions, organizations can prevent unauthorized hardware from accessing sensitive resources or networks. 

#### *Configuration*

#### *Conclusion*&#x20;

The MAC Address Restrictions feature in Skillmine Auth provides administrators with the tools to manage access control at the device level. \
By grouping and registering MAC addresses, administrators can control which devices are permitted to connect, monitor updates, and maintain compliance with security policies.&#x20;

It’s an essential configuration page for enhancing network-level security, ensuring that only trusted hardware can interact with your authentication environment.&#x20;

**Note:** Once the MAC Address Restriction policy is enforced, users attempting to log in from **unregistered devices** or **non-Skillmine browsers** will be restricted from accessing the application.\
It is recommended that all authorized users install and use the **Skillmine Auth Browser** to ensure uninterrupted and compliant access.
