Experts widely agree that username and password-based authentication is comparatively easy for cybersecurity attackers to compromise. It’s best practice to enforce key-based authentication, via protocols like mutual transport layer security (TLS) and secure shell (SSH), whenever possible. GaraSign simplifies the implementation of key-based authentication and gives customers the ability to add granular controls, such as multi-factor authentication (MFA) and device authentication, without needing to manually reconfigure servers or modify existing applications.
