Trust Login is a cloud-based identity and access management service from GMO GlobalSign Inc., part of the GMO Internet Group. It provides single sign-on (SSO), identity management, and access control with support for over 8,500 application templates, the most among Japanese Identity as a Service (IDaaS) platforms.

The platform supports SAML authentication, custom SAML app registration, and Form-based authentication integration through browser extensions and dedicated apps. It includes group management, bulk user registration via CSV, identity federation with Google Workspace and Microsoft 365, and IP-based access restrictions.

The service offers a completely free plan with unlimited accounts and apps for basic SSO and identity management, removing financial barriers so small teams can implement enterprise-grade identity management without upfront investment.
