What is AWS Secrets Manager?
In the past, when you created a custom application to retrieve information from a database, you typically embedded the credentials, the secret, for accessing the database directly in the application. When the time came to rotate the credentials, you had to do more than just create new credentials. You had to invest time to update the application to use the new credentials. Then you distributed the updated application. If you had multiple applications with shared credentials and you missed updating one of them, the application failed. Because of this risk, many customers choose not to regularly rotate credentials, which effectively substitutes one risk for another.
Secrets Manager enables you to replace hardcoded credentials in your code, including passwords, with an API call to Secrets Manager to retrieve the secret programmatically. This helps ensure the secret can't be compromised by someone examining your code, because the secret no longer exists in the code. Also, you can configure Secrets Manager to automatically rotate the secret for you according to a specified schedule. This enables you to replace long-term secrets with short-term ones, significantly reducing the risk of compromise.
For a list of terms and concepts you need to understand to make full use of Secrets Manager, see Get started with AWS Secrets Manager.

Basic AWS Secrets Manager scenario
The following diagram illustrates the most basic scenario. The diagram displays you can store credentials for a database in Secrets Manager, and then use those credentials in an application to access the database.

-
The database administrator creates a set of credentials on the Personnel database for use by an application called MyCustomApp. The administrator also configures those credentials with the permissions required for the application to access the Personnel database.
-
The database administrator stores the credentials as a secret in Secrets Manager named
MyCustomAppCreds
. Then, Secrets Manager encrypts and stores the credentials within the secret as the protected secret text. -
When MyCustomApp accesses the database, the application queries Secrets Manager for the secret named
MyCustomAppCreds
. -
Secrets Manager retrieves the secret, decrypts the protected secret text, and returns the secret to the client app over a secured (HTTPS with TLS) channel.
-
The client application parses the credentials, connection string, and any other required information from the response and then uses the information to access the database server.
Secrets Manager supports many types of secrets. However, Secrets Manager can natively rotate credentials for supported AWS databases without any additional programming. However, rotating the secrets for other databases or services requires creating a custom Lambda function to define how Secrets Manager interacts with the database or service. You need some programming skill to create the function. For more information, see Rotate AWS Secrets Manager secrets.
Features of AWS Secrets Manager
Programmatically retrieve encrypted secret values at runtime
Secrets Manager helps you improve your security posture by removing hard-coded credentials from your application source code, and by not storing credentials within the application, in any way. Storing the credentials in or with the application subjects them to possible compromise by anyone who can inspect your application or the components. Since you have to update your application and deploy the changes to every client before you can deprecate the old credentials, this process makes rotating your credentials difficult.
Secrets Manager enables you to replace stored credentials with a runtime call to the Secrets Manager Web service, so you can retrieve the credentials dynamically when you need them.
Most of the time, your client requires access to the most recent version of the encrypted secret value. When you query for the encrypted secret value, you can choose to provide only the secret name or Amazon Resource Name (ARN), without specifying any version information at all. If you do this, Secrets Manager automatically returns the most recent version of the secret value.
However, other versions can exist at the same time. Most systems support secrets more complicated than a simple password, such as full sets of credentials including the connection details, the user ID, and the password. Secrets Manager allows you to store multiple sets of these credentials at the same time. Secrets Manager stores each set in a different version of the secret. During the secret rotation process, Secrets Manager tracks the older credentials, as well as the new credentials you want to start using, until the rotation completes.
Store different types of secrets
Secrets Manager enables you to store text in the encrypted secret data portion of a secret. This typically includes the connection details of the database or service. These details can include the server name, IP address, and port number, as well as the user name and password used to sign in to the service. For details on secrets, see the maximum and minimum values. The protected text doesn't include:
-
Secret name and description
-
Rotation or expiration settings
-
ARN of the KMS key associated with the secret
-
Any attached AWS tags
Encrypt your secret data
Secrets Manager encrypts the protected text of a secret by using AWS Key Management Service (AWS KMS). Many AWS services use AWS KMS for key storage and encryption.
AWS KMS ensures secure encryption of your secret when at rest. Secrets Manager associates every secret
with a KMS key. It can be either AWS managed key for Secrets Manager for the account (aws/secretsmanager
), or a
customer managed key you create in AWS KMS.
Whenever Secrets Manager encrypt a new version of the protected secret data, Secrets Manager requests AWS KMS to generate a new data key from the KMS key. Secrets Manager uses this data key for envelope encryption. Secrets Manager stores the encrypted data key with the protected secret data. Whenever the secret needs decryption, Secrets Manager requests AWS KMS to decrypt the data key, which Secrets Manager then uses to decrypt the protected secret data. Secrets Manager never stores the data key in unencrypted form, and always disposes the data key immediately after use.
In addition, Secrets Manager, by default, only accepts requests from hosts using open standard
Transport Layer
Security (TLS)
Automatically rotate your secrets
You can configure Secrets Manager to automatically rotate your secrets without user intervention and on a specified schedule.
You define and implement rotation with an AWS Lambda function. This function defines how Secrets Manager performs the following tasks:
-
Creates a new version of the secret.
-
Stores the secret in Secrets Manager.
-
Configures the protected service to use the new version.
-
Verifies the new version.
-
Marks the new version as production ready.
Staging labels help you to keep track of the different versions of your secrets. Each
version can have multiple staging labels attached, but each staging label can only be
attached to one version. For example, Secrets Manager labels the currently active and in-use
version of the secret with AWSCURRENT
. You should configure your applications to always
query for the current version of the secret. When the rotation process creates a new version
of a secret, Secrets Manager automatically adds the staging label
to
the new version until testing and validation completes. Only then does Secrets Manager add the
AWSPENDING
AWSCURRENT
staging label to this new version. Your applications immediately start using
the new secret the next time they query for the AWSCURRENT
version.
Databases with fully configured and ready-to-use rotation support
When you choose to enable rotation, Secrets Manager supports the following Amazon Relational Database Service (Amazon RDS) databases with AWS written and tested Lambda rotation function templates, and full configuration of the rotation process:
-
Amazon Aurora on Amazon RDS
-
MySQL on Amazon RDS
-
PostgreSQL on Amazon RDS
-
Oracle on Amazon RDS
-
MariaDB on Amazon RDS
-
Microsoft SQL Server on Amazon RDS
Other services with fully configured and ready-to-use rotation support
You can also choose to enable rotation on the following services, fully supported with AWS written and tested Lambda rotation function templates, and full configuration of the rotation process:
-
Amazon DocumentDB
-
Amazon Redshift
You can also store secrets for almost any other kind of database or service. However, to automatically rotate the secrets, you need to create and configure a custom Lambda rotation function. For more information about writing a custom Lambda function for a database or service, see How rotation works.
Control access to secrets
You can attach AWS Identity and Access Management (IAM) permission policies to your users, groups, and roles that grant or deny access to specific secrets, and restrict management of those secrets. For example, you might attach one policy to a group with members that require the ability to fully manage and configure your secrets. Another policy attached to a role used by an application might grant only read permission on the one secret the application needs to run.
Alternatively, you can attach a resource-based policy directly to the secret to grant
permissions specifying users who can read or modify the secret and the versions. Unlike an
identity-based policy which automatically applies to the user, group, or role, a
resource-based policy attached to a secret uses the Principal
element to
identify the target of the policy. The Principal
element can include users and
roles from the same account as the secret or principals from other accounts.
