Authentication with Loki

OperationsAuthentication

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. For more information on multi-tenancy please read its documentation.

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