The October 2025 release of Administrator includes the following important notices.
Deprecation notice
Effective in the October 2025 release, session-based authentication is deprecated. Informatica intends to drop support for session-based authentication in the October 2026 release.
Deprecated functionality is supported, but Informatica intends to drop support in a future release. Informatica requests that you transition to different functionality before the functionality is dropped.
Informatica plans to replace session IDs used for user authentication with JSON Web Tokens (JWT). Organization administrators have the option to use either session-based authentication or JWT-based authentication on the Settings page in Administrator. When JWT authentication is enabled, browser-based user interface communications 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 Settings page. As a result, REST API scripts need to be updated to handle automatic re-authentication before or after the token expires. For more information, see the JWT Support Knowledge article.
In the October 2025 release, session-based authentication is the default. In the April 2026 release, JWT is the default authentication method. By October 2026, session-based authentication will no longer be available.
Note: If your organization uses B2B Gateway, API Manager, or the REST V2 Connector, don't select the JWT option in the October 2025 release. The JWT option for B2B Gateway and REST V2 Connector will be available in a future release.
