Grafana Loki Operations Authentication

Authentication with Grafana Loki

Grafana Loki does not come with any included authentication layer. Operators are expected to run an authenticating reverse proxy in front of your services, such as NGINX using basic auth or an OAuth2 proxy.

Note that when using Loki in multi-tenant mode, Loki requires the HTTP header X-Scope-OrgID to be set to a string identifying the tenant; the responsibility of populating this value should be handled by the authenticating reverse proxy. Read the multi-tenancy documentation for more information.

For information on authenticating Promtail, please see the docs for how to configure Promtail.
