Authentication and platform access
General overview
Access to the Gnorm platform is provided through the Access button located in the top navigation bar of the interface. The system supports two authentication methods:
- Direct ITSERR access – via system-provided credentials (username and password);
- Federated D4Science access – via external academic or institutional providers (Google, LinkedIn, ORCID, GitHub, CNR-ISTI, etc.).
Direct ITSERR access
The ITSERR login page allows users to enter:
- Username
- Password
and proceed using the Log in button.
Alternatively, users can authenticate directly through the ITSERR Account button, which automatically redirects to the centralized authentication portal, maintaining the user session active for the entire duration of navigation.
Federated access via D4Science
Federated authentication is managed through Keycloak, a secure system compliant with the digital identity standards adopted by D4Science. From the login screen, users can choose among several academic or third-party providers, including:
- Academic / Other
- Google
- LinkedIn
- Twitter
- GitHub
- ORCID
- CNR-ISTI
Users may also enable the Remember me option to keep the session active or use Forgot Password to recover credentials. Once authentication is completed, the user is redirected to the authenticated homepage of the platform.
Session management
After authentication:
- The Access button in the top navigation bar is replaced by Logout;
- The user can freely navigate between corpora, perform searches, and use advanced functionalities;
- Upon browser closure or prolonged inactivity, the session is automatically terminated.

Security and credential management
The system guarantees:
- Secure HTTPS connections for all requests;
- Centralized credential management via D4Science;
- Automatic session expiration to prevent unauthorized access;
- SSO (Single Sign-On) compatibility for integration with other ITSERR modules.
