 In SQL Server, this type of connection is called **SQL Server Authentication**.  Many other database data sources provide a similar capability.  When you publish your application, your users don't need to supply a unique user name and password.  They're using the user name and password you supply when you author the application.  The connection authentication to the data source is **Implicitly Shared** with your users.  Once the application is published, the connection is also published and available to your users.  Your end users can also create applications using any connection using SQL Server authentication that is shared with them.  Your users can't see the user name or password, but the connection will be available to them.  **There are valid scenarios for this type of connection. For instance if you have a read-only database that is available to everyone in the company. Reference data scenarios (for example, a corporate calendar) can be useful for this kind of connection.** More information: [Use Microsoft SQL Server securely with Power Apps](connections/sql-server-security.md)
 
-### Secure Implicit Connections (Preview, default ON)
-Power Apps now has full preview support for **[Secure implicit connections)](working-with-experimental-preview.md)**.  The default setting for this feature is On.  The secure implicit shared connections are more secure than the existing implicit connections. Power Apps implicitly shared connections are ones that use a fixed credential such as a SQL Server connection string rather than the end user's specific credentials such as AAD. With this feature, connections are no longer directly shared with the users of Power Apps. Instead, a proxy connection object that only grants access to the underlying resource such as a specific SQL server table is shared. End user authors can't create new applications with either the connection or the proxy connection. This feature also limits the end user to such actions as **get**, **put/patch**, and **delete** that are defined in the corresponding app. The result is that end users who are also authors can't create new applications with either the connection or the proxy connection object.
