+# Data Source: aws_redshiftserverless_credentials
+
+Provides redshift serverless temporary credentials for a workgroup.
+
+## Example Usage
+
+```terraform
+data "aws_redshiftserverless_credentials" "example" {
+  workgroup_name = aws_redshiftserverless_workgroup.example.workgroup_name
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `workgroup_name` - (Required) The name of the workgroup associated with the database.
+* `db_name` - (Optional) The name of the database to get temporary authorization to log on to.
+* `duration_seconds` - (Optional) The number of seconds until the returned temporary password expires. The minimum is 900 seconds, and the maximum is 3600 seconds.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `db_password` - Temporary password that authorizes the user name returned by `db_user` to log on to the database `db_name`.
+* `db_user` - A database user name that is authorized to log on to the database `db_name` using the password `db_password` . If the specified `db_user` exists in the database, the new user name has the same database privileges as the the user named in `db_user` . By default, the user is added to PUBLIC. the user doesn't exist in the database.
+* `expiration` - Date and time the password in `db_password` expires.
