+title: Authenticating to Cockpit's Grafana using IAM
+description: Learn how to transition from Grafana credentials authentication to Scaleway IAM to access your Cockpit's Grafana
+dates:
+  validation: 2025-08-20
+  posted: 2025-08-20
+---
+
+Starting **October 1st, 2025**, Cockpit will be integrated with **Scaleway IAM**, enabling you to authenticate to your Cockpit's Grafana using your **Scaleway credentials** rather than Grafana credentials.
+
+This page explains how to prepare for the transition.
+
+
+## Reasons for the change
+
+We are simplifying authentication and improving security by:
+
+- Removing the need to manage Grafana-specific users and passwords.
+- Enabling login using your existing **Scaleway credentials**.
+- Allowing central IAM-based access management.
+- Supporting **Multi-Factor Authentication (MFA)**.
+
+## Transition timeline
+
+| Event | Date |
+|------|------|
+| IAM authentication becomes available | **October 1st, 2025** |
+| Creating new Grafana users disabled | **October 1st, 2025** |
+| Legacy Grafana user login deprecation | **January 20th, 2026** |
+
+
+## What is changing?
+
+### New login method
+
+From **October 1st**, you will be able to log in using your Scaleway credentials via the Scaleway console or saved links.
+
+### New dashboard URLs
+
+To support both login methods during the transition, Grafana dashboards will have **new URLs**:
+
+- **Old URL:**
+  `https://<project_id>.dashboard.obs.fr-par.scw.cloud`
+
+- **New URL (IAM-authenticated):**
+  `https://<project_id>.dashboard.cockpit.scaleway.com`
+  or
+  `https://<project_id>.dashboard.cockpit.scw.cloud`
+
+Both links will be functional until **January 20th, 2026**, after which only the new IAM-based URLs will remain valid.
+
+## Who can access your Cockpit's Grafana?
+
+Users must:
+
+- Be **members** of your Scaleway Organization
+- Have access to the Scaleway Project where the Cockpit is located
+- Have been granted either the `ObservabilityReadOnly` or the `ObservabilityFullAccess` IAM permission set
+
+You can manage members and permission sets in the [IAM section of the Scaleway console](https://console.scaleway.com/iam/members).
+
+
+## How to access your Cockpit's Grafana?
+
+### From the Scaleway console
+
+Access to Grafana using the Scaleway console remains the same as before.
+
+1. Click **Cockpit** in the **Monitoring** section of the [console](https://console.scaleway.com/) side menu. The **Cockpit** overview page displays.
+2. Click **Open dashboards** to open your preconfigured dashboards in Grafana. You will be automatically logged in using your Scaleway account.
+
+### From a saved/shared link
+
+You can also access your Cockpit's Grafana using bookmarked links, alerts, or runbooks.
+
+1. Open the new IAM-compatible URL. The Scaleway login page displays.
+2. Log in using your Scaleway credentials. Your Grafana dashboard displays.
+
+## What will happen to existing Grafana users?
+
+Grafana users not linked to Scaleway IAM will be deprecated. Refer to the table below to find out until when you can perform which actions.
+
+| Action | Available until |
+|--------|-----------------|
+| Log in using Grafana credentials | **January 20th, 2026** |
+| Generate passwords for existing Grafana users | **January 20th, 2026** |
+| Create new Grafana users | **Disabled after October 1st, 2025** |
+
+## How to prepare for this transition?
+
+If you have users who are not in your Scaleway Organization, we recommend the following:
+
+- **Invite them as Members** to your Organization
+- Assign the `ObservabilityReadOnly` or the `ObservabilityFullAccess` permission sets only to the Projects they need to access
