Operators are 8 expected to run an authenticating reverse proxy in front of your services, such 9 as NGINX using basic auth or an OAuth2 proxy. 10 11 Note that when using Loki in multi-tenant mode, Loki requires the HTTP header 12 `X-Scope-OrgID` to be set to a string identifying the tenant; the responsibility 13 of populating this value should be handled by the authenticating reverse proxy. 14 Read the [multi-tenancy](../multi-tenancy/) documentation for more information. 15 16 For information on authenticating Promtail, please see the docs for [how to 17 configure Promtail](../../clients/promtail/configuration/).
