What is the default user authentication method used by the firewall?

The default user authentication method used by SonicWall firewalls is Local Users. This means the firewall is configured to manage user authentication internally, relying on a database of users that is stored directly within the firewall itself. Local user accounts are created and managed directly through the firewall's management interface, allowing for a straightforward setup without the need for external integration or services.

Using local users as the default method provides simplicity and quick deployment, especially in smaller environments where complex user management systems may not be necessary. This setup ensures that administrators can quickly add or remove users and assign permissions without relying on external resources.

In contrast, other authentication methods like Active Directory, RADIUS, or External Database require integration with other systems, which can complicate configuration and maintenance. For many users, particularly in smaller businesses or for initial configurations, having a default option that is easy to manage makes local users the ideal choice.
