The goal of this guide is to help users understand the available login methods, when to use each one, and what to expect as EWC moves toward a fully integrated identity experience. It provides a clear overview of how users authenticate to services within the European Weather Cloud (EWC).
EWC introduced a unified identity system based on EWC IAM. All EWC services will be accessible with the same user credentials in the future. EWC IAM can federate with other existing IAMs as well (e.g. ECMWF IAM, EUMETSAT User Portal). While we transition to the use of EWC IAM, some services might still support local accounts. You can check the table below for more details.
A local account is a username and password stored within a single EWC service, managed independently by that service. An EWC IAM user authenticates through the central identity system using institutional credentials and gains unified access across IAM‑enabled EWC services.
Tenancy name is the input to start with EWC IAM!
When you log in to an EWC service using IAM Single Sign-On, your browser keeps your session active. If you need to access another tenancy, you must log out of the service first before logging in again. Alternatively, you can open the service in another browser or use a private/incognito window to avoid session conflicts.
