+
+**Note:** v1 database credentials are now deprecated and only maintained for backward compatibility. v2 database credentials should be used for any new connections.
+
+When adding a v1 database credential a database connection string was required. This required a separate database credential for each database instance to monitor even if the username and password were the same! To address this, v2 database credentials only contain username and password.
+
+Connection strings are now required when defining a proxied device for a database connection. This allows you to use the same database credential for multiple database connections. It also means there is only one credential to update when its password expires.
+
+For more information on v2 database credentials, see the [v8.1 release notes](https://community.netwrix.com/t/minor-version-8-1-released/2829)
