+Allowed fields: `["apps", "synced", "outOfSync", "healthy", "progressing", "degraded", "suspended", "missing"]`
+
+```yaml
+widget:
+  type: argocd
+  url: http://argocd.host.or.ip:port
+  key: argocdapikey
+```
+
+You can generate an API key either by creating a bearer token for an existing account, see [Authorization](https://argo-cd.readthedocs.io/en/latest/developer-guide/api-docs/#authorization) (not recommended) or create a new local user account with limited privileges and generate an authentication token for this account. To do this the steps are:
+
+- [Create a new local user](https://argo-cd.readthedocs.io/en/stable/operator-manual/user-management/#create-new-user) and give it the `apiKey` capability
+- Setup [RBAC configuration](https://argo-cd.readthedocs.io/en/stable/operator-manual/rbac/#rbac-configuration) for your the user and give it readonly access to your ArgoCD resources, e.g. by giving it the `role:readonly` role.
+- In your ArgoCD project under _Settings / Accounts_ open the newly created account and in the _Tokens_ section click on _Generate New_ to generate an access token, optionally specifying an expiry date.
+
+If you installed ArgoCD via the official Helm chart, the account creation and rbac config can be achived by overriding these helm values:
+
+```yaml
+configs:
+  cm:
+    accounts.readonly: apiKey
+  rbac:
+    policy.csv: "g, readonly, role:readonly"
+```
+
+This creates a new account called `readonly` and attaches the `role:readonly` role to it.
