What is AWS Secrets Manager?

AWS Secrets Manager helps you manage, retrieve, and rotate database credentials, API keys, and other secrets throughout their lifecycle. It provides secure storage with encryption using KMS and automatic rotation capabilities for supported databases including RDS, Aurora, and Redshift. Secrets Manager integrates with IAM for access control and CloudTrail for audit logging. You can programmatically retrieve secrets using the Secrets Manager API, eliminating the need to hardcode sensitive information in application code. It supports versioning of secrets and provides fine-grained access policies. Secrets Manager charges based on the number of secrets stored and API calls made, offering a more comprehensive solution than Systems Manager Parameter Store for secret management.
