Amazon RDS now supports integration with AWS Secrets Manager to streamline how you manage your master user password for your RDS database instances. With this feature, RDS fully manages the master user password and stores it in AWS Secrets Manager whenever your RDS database instances are created, modified, or restored. The new feature supports the entire lifecycle maintenance for your RDS master user password including regular and automatic password rotations; removing the need for you to manage rotations using custom Lambda functions.
