     5  # Authentication with Grafana Loki
     6  
     7  Grafana Loki does not come with any included authentication layer. 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/).
