The October 2025 release of Administrator includes the following important notices.
JSON web tokens and session IDs
Informatica plans to replace session IDs used for user authentication with JSON Web Tokens (JWT). Starting on November 3, 2025, organization administrators will have the option to switch from session-based to JWT-based authentication on the Organization page in Administrator. Once enabled, browser-based user interface communications will seamlessly use JWT behind the scenes.
For REST API calls, session IDs must still be included in request headers as usual. However, now the session value carries a JWT with a fixed expiry time configured on the Organization page. As a result, REST API scripts will need to be updated to handle automatic re-authentication before or after the token expires.
In the October 2025 release, session-based authentication will remain the default. Starting in April 2026, JWT will become the default authentication method. By July 2026, session-based authentication will no longer be available.
Note: If your organization uses B2B Gateway, don't select the JWT option in the October 2025 release. The JWT option for B2B Gateway will be available in the April 2026 release.
