AWS Access Keys. Access Keys are used to sign the requests you send to Amazon S3. Like the Username/Password pair you use to access your AWS Management Console, Access Key Id and Secret Access Key are used for programmatic (API) access to AWS services. You can manage your Access Keys in AWS Management Console. Ssh-keygen -f YOURPEMFILE.pem -y It will generate a key. Append the key to /.ssh/authorizedkeys opened in step#1. No need to delete the old key. From AWS console, create a new key pair. Store it in your new machine. Rename it to the old pem file - reason is old pem file is still associated with the ec2 instance in AWS. An access key grants programmatic access to your resources. This means that the access key should be guarded as carefully as the AWS account root user sign-in credentials. Create an IAM user and then define that user's permissions as narrowly as possible. Create the access key under that IAM user. An access key grants programmatic access to your resources. This means that the access key should be guarded as carefully as the AWS account root user sign-in credentials. It's a best practice to do the following: Create an IAM user and then define that user's permissions as narrowly as possible. Create the access key under that IAM user.

This Python example shows you how to manage the access keys of your users.

The Scenario¶

Users need their own access keys to make programmatic calls to AWS from the Amazon Web Services (AWS)SDK for Python. To fill this need, you can create, modify, view, or rotate access keys(access key IDs and secret access keys) for IAM users. By default, when you create an access key, itsstatus is Active, which means the user can use the access key for API calls.

In this example, Python code is used to manage access keys in IAM. The code uses the AWS SDK for Pythonto manage IAM access keys using these methods of the IAM client class:

• create_access_key.
• paginate(UserName='IAM_USER_NAME').
• get_access_key_last_used.
• update_access_key.
• delete_access_key.

For more information about IAM access keys, see Managing Access Keysin the IAM User Guide.

All the example code for the Amazon Web Services (AWS) SDK for Python is available here on GitHub.

Prerequisite Task¶

To set up and run this example, you must first configure your AWS credentials, as described in Quickstart.

Create Access Keys for a User¶

Create a new AWS secret access key and corresponding AWS access key ID for the specified user. Thedefault status for new keys is Active.

The example below shows how to:

• Create a new AWS access key usingcreate_access_key.

List a User's Access Keys¶

List information about the access key IDs associated with the specified IAM user. If there are none,the action returns an empty list.

If the UserName field is not specified, the UserName is determined implicitly based on the AWS accesskey ID used to sign the request. Because this action works for access keys under the AWS account,you can use this action to manage root credentials even if the AWS account has no associated users.

The example below shows how to:

• List a user's access keys usingpaginate(UserName='IAM_USER_NAME').

For more information about paginators see, Paginators

Get the Access Key Last Used¶

Get information about when the specified access key was last used. The information includes thedate and time of last use, along with the AWS service and region that were specified in the last requestmade with that key.

The example below shows how to:

• Get the access key last used usingget_access_key_last_used.

Update Access Key Status¶

Change the status of the specified access key from Active to Inactive, or vice versa. This actioncan be used to disable a user's key as part of a key rotation work flow.

The example below shows how to:

• Change the status of an access key to Active usingupdate_access_key.

Delete an Access Key¶

Delete the access key pair associated with the specified IAM user.

If you do not specify a user name, IAM determines the user name implicitly based on the AWS accesskey ID signing the request. Because this action works for access keys under the AWS account, you canuse this action to manage root credentials even if the AWS account has no associated users.

The example below shows how to:

• Delete an access key usingdelete_access_key.

Root Access Keys provide unlimited access to your AWS resources. It's not recommended to use them in normal situations. AWS recommends to delete existing Root Access Keys and create IAM user and Access Keys limited to specific service or resource (see below).

To Delete Root Access Keys

1. Type https://aws.amazon.com/ in your web browser

2. Click My Account, AWS Management Console

3. Enter your account email address and password:

4. Type the IAM in the search box and choose the IAM service from the drop-down list.

You will be redirected to IAM Dashboard

5. Navigate to Security Status and expand the Delete your root access keys section.

6. Click Manage Security Credentials

7. Click Continue to Security Credentials

Create New Access Key Aws

Your Security Credentials page will open

8. Expand the Access Keys (access key id and secret acces key) section

9. Click the Delete link next to your access keys row.

Create Access Key Aws

10. Confirm Access Keys deletion.

11. Your Root Access Keys are deleted. Now you can create IAM user and Access Keys limited to specific service or resource (see below).

Generate New Access Key Aws Server

Be sure to replace your root access keys with your IAM access keys in any programs/scripts you are currently using.
