Description
The Authentication subkey stores configuration data for Routing and Remote Access authentication providers, such as Windows and Remote Authentication Dial-In User Service (RADIUS).
The Authentication subkey does not contain any entries. It contains a Authentication\Providers Subkey subkey, which contains entries that apply to all dial-up authentication providers and subkeys that represent each provider and that store provider-specific entries.
