IAM List Access Keys

Here’s how to list all the access keys in AWS via Python.
import logging
import boto3
from botocore.exceptions import ClientError
 
# set aws profile
session = boto3.Session(profile_name="default")
 
# get list of users
 
iam = session.client('iam')
users = iam.list_users()
 
# display results
print("{0:<20} {1:<25} {2:<15} {3:<10}".format('UserName', 'AccessKey', 'Status', 'CreateDate'))
print("----------------------------------------------------------------------------------------")
 
for a in users['Users']:
    user = a['UserName']
    # get keys
    keys = iam.list_access_keys(UserName=user)
    for b in keys['AccessKeyMetadata']:
        username = b['UserName']
        accesskeyid = b['AccessKeyId']
        status = b['Status']
        createdate = str(b['CreateDate'])
        print("{0:<20} {1:<25} {2:<15} {3:<10}".format(username, accesskeyid, status, createdate))
