aws_easy_mfa is a simple wrapper for AWS's boto3 that makes it much simpler to use with MFA.
Simply wrap any function invoking a boto3 session with the aws_easy_mfa decorator and you're off! aws_easy_mfa will take care of all the tedius MFA login steps.
You can install aws_easy_mfa via pip
pip install aws-easy-mfaUsing boto3 to list bucket names in s3 with the aws_easy_mfa decorator.
from aws_easy_mfa import aws_easy_mfa
@aws_easy_mfa(mfa_device_arn='arn-of-the-mfa-device',
mfa_token_code='code-from-token')
def list_s3_buckets(session=None):
# Create an S3 client using the session
s3_client = session.client('s3')
# List all S3 buckets
response = s3_client.list_buckets()
# Extract the bucket names from the response
buckets = response['Buckets']
bucket_names = [bucket['Name'] for bucket in buckets]
return bucket_namesYou can control your MFA timeout by including duration_seconds as shown below
@aws_easy_mfa(mfa_device_arn='arn-of-the-mfa-device',
mfa_token_code='code-from-token',
duration_seconds=3600)
def list_s3_buckets(session=None):
...In addition, if you would like your MFA-authorized sesssion for further usage, you can add the return_session=True flag to your decorator, like this
@aws_easy_mfa(mfa_device_arn='arn-of-the-mfa-device',
mfa_token_code='code-from-token',
duration_seconds=3600,
return_session=True)
def list_s3_buckets(session=None):
...The session is returned as a second argument. So for example instead of
bucket_names = list_s3_buckets()enabling this flag returns your session as
bucket_names, session = list_s3_buckets()You can also create an MFA session without usage of the decorator as shown below:
from aws_easy_mfa.utilities import get_mfa_credentials, create_boto3_session
# get credentials
credentials = get_mfa_credentials(mfa_device_arn='arn-of-the-mfa-device',
mfa_token_code='code-from-token',
duration_seconds)
# generate mfa-authorized session
session = create_boto3_session(credentials)
