You can define a dynamic AWS secret to dynamically generate AWS access credentials based on IAM policies.

You can create dynamic access credentials for AWS in two modes:

iam_user mode: When a client requests a dynamic secret value, a temporary IAM user is created for the requested AWS account, and an access key is returned to the client.

Although the temporary IAM user's access can be revoked at any time, temporary IAM users can only be created with access to a single AWS account. If you have multiple AWS accounts, you will need to create a separate dynamic secret for each account.

assumed_role mode: When a client requests the dynamic secret value, an AssumeRole operation is performed to return an access key, secret key, and session token.

Although a single dynamic secret can assume roles for multiple accounts, due to AWS limitations, once access is granted, it cannot be revoked before its defined expiration time (a minimum of 15 minutes and a maximum of 12 hours).

An Akeyless Gateway.

To define a dynamic secret for AWS, you first need to configure Akeyless to authenticate and communicate with AWS as follows:

Create an AWS IAM user with privileged administrator access.
Retrieve the access key ID and secret access key for the new AWS IAM user. These credentials are required to authenticate with AWS.
- If you are using iam_user mode, the minimum required policy for the user should include the following permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "iam:DeleteAccessKey",
                "iam:AttachUserPolicy",
                "iam:DeleteUser",
                "iam:ListUserPolicies",
                "iam:CreateUser",
                "iam:TagUser",
                "iam:CreateAccessKey",
                "iam:CreateLoginProfile",
                "iam:RemoveUserFromGroup",
                "iam:AddUserToGroup",
                "iam:ListGroupsForUser",
                "iam:ListAttachedUserPolicies",
                "iam:DetachUserPolicy",
                "iam:GetLoginProfile",
                "iam:DeleteLoginProfile",
                "iam:ListUserTags",
                "iam:ListAccessKeys"
            ],
            "Resource": "arn:aws:iam::<your-aws-account-id>:user/*"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "iam:ListPolicies",
                "iam:ListRoles",
                "iam:ListUsers",
                "iam:ListGroups"
            ],
            "Resource": "*"
        }
    ]
}

AWS IAM Tip
You can create a new user and attach the policy above for the purposes of authenticating with AWS.

If you are using assumed_role mode, grant the user AssumeRole permissions to the requested IAM roles. For for more information see the AWS Assume Role documentation.

Create a Dynamic AWS Secret from the CLI

👍
Tip
We recommend using dynamic secrets with [Targets](https://docs.akeyless.io/docs/aws-targets. To save time on the secret configuration for different types of access permissions. Where you are not required to provide an inline connection strings each time.

To create a dynamic AWS secret from the CLI using an existing AWS Target, run the following command:

akeyless gateway-create-producer-aws \
--name <secret name> \
--target-name <Target Name> \
--gateway-url 'https:\\<Your-Akeyless-GW-URL:8000>' \
--aws-access-mode <iam_user|assumed_role> \
--aws-user-policies <Policy ARN> \
--aws-user-groups <UserGroup name> \
--aws-role-arns <AWS Role ARNs>

Or using an inline connection string:

akeyless gateway-create-producer-aws \
--name <secret name> \
--gateway-url 'https:\\<Your-Akeyless-GW-URL:8000>' \
--aws-access-mode <iam_user|assumed_role> \
--aws-user-policies <Policy ARN> \
--aws-user-groups <UserGroup name> \
--aws-role-arns <AWS Role ARNs> \
--aws-access-key-id <Access ID> \
--aws-access-secret-key <Access Key> \
--aws-region <Region>

Where:

name: A unique name of the dynamic secret. The name can include the path to the virtual folder where you want to create the new dynamic secret, using slash / separators. If the folder does not exist, it will be created together with the dynamic secret.
target-name: A name of the target that enables connection to the AWS. The name can include the path to the virtual folder where this target resides.
gateway-url: Akeyless Gateway URL.
aws-access-mode: The types of credentials to retrieve from AWS. The following options are available:

iam_user or assume_role.
aws-user-policies: Policy ARN(s). Multiple values should be separated by a comma. User will be granted these policies when the dynamic secret is created.
aws-user-groups: UserGroup name(s). Multiple values should be separated by a comma.
aws-role-arns: AWS Role ARNs to be used in the Assume Role operation. Multiple values should be separated by a comma.

Inline connection strings

If you don't have a configured AWS Target yet, you can use the command with target AWS account connection settings:

aws-access-key-id: The Access ID of the privileged user you created to authenticate Akeyless with AWS.
aws-access-secret-key: The Access Key of the privileged user you created to authenticate Akeyless with AWS.
aws-region: The AWS region that the temporary credentials are permitted to access.

You can find the complete list of parameters for this command in the CLI Reference - Akeyless Producers section.

Fetch a Dynamic AWS Secret value from the CLI

To fetch a dynamic AWS secret value from the CLI, run the following command:

Create a Dynamic AWS Secret in the Akeyless Console

👍
Tip
To start working with dynamic secrets from the Akeyless Console, you need to configure the Gateway URL thus enabling communication between the Akeyless SaaS and the Akeyless Gateway.
To create dynamic secrets directly from the Akeyless Gateway, you can use the Gateway Configuration Manager.

Log in to the Akeyless Console, and go to Secrets & Keys > New > Dynamic Secret.
Select the AWS secret type and click Next.
Define a Name of the dynamic secret, and specify the Location as a path to the virtual folder where you want to create the new dynamic secret, using slash / separators. If the folder does not exist, it will be created together with the dynamic secret.
Define the remaining parameters as follows:

Delete Protection: When enabled, protects the secret from accidental deletion.
Target mode: In this section, you can either select an existing AWS Target or specify details of the target AWS account explicitly.
- Use the Choose an existing target drop-down list to select the existing AWS Target .
- Check the Explicitly specify target properties to provide details of the target AWS account in the next step.
Access Mode: Select the AWS access mode, either IAM User or Assume Role.
Policies: Provide the individual Policy ARN(s) available for this dynamic secret. Multiple values should be separated by a comma.
Groups: Provide the UserGroup name(s). Multiple values should be separated by a comma.
Role ARNs: Provide the allowed AWS Role ARNs to be used in the Assume Role mode.
User Programmatic Access: Check to enable an Access ID and Access Key for the AWS API, CLI, SDK.
User Console Access: Check to enable access to the AWS management console. (The returned object will include a username and password to connect to the AWS Management Console).
User TTL: Provide a time-to-live value for a dynamic secret (i.e., a token). When TTL expires, the token becomes obsolete.
Time Unit: Select the time unit (seconds, minutes, hours) for the TTL value.
Gateway: Select the Gateway through which the dynamic secret will create users.
Protection key: To enable zero-Knowledge, select a key with a Customer Fragment. For more information about zero-Knowledge, see Implement Zero Knowledge

If you checked the Explicitly specify target properties, click Next.
Provide details of the target AWS account:

Access Key ID: Specify the Access ID assigned to the admin user you created to authenticate Akeyless with AWS.
Secret Access Key: Specify the Access Key assigned to the admin user you created to authenticate Akeyless with AWS.
Region: Enter the AWS region that the temporary credentials are permitted to access.
Session Token: Token is required only for temporary security credentials retrieved via STS. Otherwise, it can be left empty.

Click Finish.

Fetch a Dynamic AWS Secret Value from the Akeyless Console

Log in to the Akeyless Console, and go to Secrets & Keys.
Browse to the folder where you created a dynamic secret.
Select the secret and click Get Dynamic Secret button.
