Utility that obtains STS credentials and saves your AWS credentials file.

Project description

AWS MFA Helper

Automate obtaining MFA (STS) credentials

This utility will request STS credentials from AWS, then update ~/.aws/credentials with the new credentials. STS credentials are stored in a profile suffixed with -mfa.

If you have TOTP Generator installed this utility will attempt to automate the TOTP code generation.

You will need to update your AWS configuration (~/.aws/config) with the following settings:

[profile my-aws-profile]
helper_mfa_serial = (your MFA ARN)
helper_totp_service_name = (Optional: service name in TOTP Generatior)

If you need to change the STS/MFA credentials suffix in the aws config file, create ~/.aws_mfa_helper.cfg with the following:

mfa_creds_suffix = your-new-suffix

Run with the --help flag for more information.
