Create an IAM User

Sign in to the AWS IAM Console and go to Users > Create user.

1

Set user name

Enter a name (e.g., stackone-s3) and click Next.

2

Attach permissions

Choose Attach policies directly and attach AmazonS3FullAccess (or a custom policy with only the S3 permissions required).

3

Generate access keys

Select the new user, go to Security credentials > Create access key, choose Third-party service, and save both the Access Key ID and Secret Access Key.

  • Save the Secret Access Key immediately — it cannot be retrieved again after creation.
