# OAuth

DataSpace supports secure user authentication through two mechanisms: **direct credential login** (username and password) and **federated single sign-on (SSO)** using trusted **OAuth 2.0 providers** such as **Microsoft** and **Google**.

Federated authentication allows organizations to leverage their existing identity providers for centralized account management and enhanced security. Passwords for OAuth users are never stored or handled by DataSpace.
