Windows Authentication


SQL Server Authentication or HTTP Basic Authentication when used with a Secure Sockets Layer (SSL) connection to the Web synchronization Web server.

With the exception of the connection to the Web server used with Web synchronization for merge replication, you should use Windows Authentication whenever possible. For more information, see Web Synchronization for Merge Replication.
