Dynamic Data Masking provides a simple authentication scheme that authenticates a user based on the Dynamic Data Masking Server password.
When you install the Dynamic Data Masking Server, you must create a password for the server. Dynamic Data Masking uses the server password for authentication when you initially log in to the Management Console.
The Management Console login requires a user name and password. The Internal authentication scheme uses only the password for authentication. It uses the user name to identify the user and to track user activity in the Management Console.
You can use the Server Control command SetInternalPassword to change the Dynamic Data Masking Server password at any time.
