Create an IAM access key using an AWS SDK - AWS SDK Code Examples

There are more AWS SDK examples available in the AWS Doc SDK Examples GitHub repo.

Create an IAM access key using an AWS SDK

The following code examples show how to create an IAM access key.

Warning

To avoid security risks, don't use IAM users for authentication when developing purpose-built software or working with real data. Instead, use federation with an identity provider such as AWS IAM Identity Center.

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code examples:

CLI
AWS CLI

To create an access key for an IAM user

The following create-access-key command creates an access key (access key ID and secret access key) for the IAM user named Bob.

aws iam create-access-key \ --user-name Bob

Output:

{ "AccessKey": { "UserName": "Bob", "Status": "Active", "CreateDate": "2015-03-09T18:39:23.411Z", "SecretAccessKey": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYzEXAMPLEKEY", "AccessKeyId": "AKIAIOSFODNN7EXAMPLE" } }

Store the secret access key in a secure location. If it is lost, it cannot be recovered, and you must create a new access key.
