# Network Server user authentication when user authentication is off in Derby

When user authentication is turned off in Derby, you can use any of the security mechanism options.

You must provide a user and password for all security mechanisms except USER_ONLY_SECURITY. However, because user authentication is disabled in the Derby server, the user name and password that you supply does not have to be one recognized as valid by Derby.
