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.

Example 1: This example creates a new access key and secret access key pair and assigns it to the user David. Ensure that you save the AccessKeyId and SecretAccessKey values to a file because this is the only time you can obtain the SecretAccessKey. You cannot retrieve it later. If you lose the secret key, you must create a new access key pair.

New-IAMAccessKey -UserName David

Output:
