Keymaker is the missing link between SSH and IAM accounts on Amazon AWS. It's a stateless synchronization engine that securely manages the process of SSH public key sharing and verification, user and group synchronization, and home directory sharing (via optional EFS integration). You, the AWS account administrator, define or import user and group identities in IAM, and instances in your account dynamically retrieve and use those identities to authenticate your users. Keymaker is the modern, minimalistic alternative to LDAP or Active Directory authentication. Run pip install keymaker.
