Security

Please read this page carefully. Although there are various ways to secure your Qdrant instances, they are unsecured by default. You need to enable security measures before production use. Otherwise, they are completely open to anyone

Authentication

Available as of v1.2.0

Qdrant supports a simple form of client authentication using a static API key. This can be used to secure your instance.

To enable API key based authentication in your own Qdrant instance you must specify a key in the configuration:

service:
  # Set an api-key.
  # If set, all requests must include a header with the api-key.
  # example header: `api-key: <API-KEY>`
  #
  # If you enable this you should also enable TLS.
  # (Either above or via an external service like nginx.)
  # Sending an api-key over an unencrypted channel is insecure.
  api_key: your_secret_api_key_here

For using API key based authentication in Qdrant cloud see the cloud Authentication section.

The API key then needs to be present in all REST or gRPC requests to your instance. All official Qdrant clients for Python, Go, and Rust support the API key parameter.

curl \
  -X GET https://localhost:6333 \
  --header 'api-key: your_secret_api_key_here'

from qdrant_client import QdrantClient

qdrant_client = QdrantClient(
    url="https://localhost",
    port=6333,
    api_key="your_secret_api_key_here",
)

TLS

Available as of v1.2.0

TLS for encrypted connections can be enabled on your Qdrant instance to secure connections.

First make sure you have a certificate and private key for TLS, usually in .pem format. On your local machine you may use mkcert to generate a self signed certificate.

To enable TLS, set the following properties in the Qdrant configuration with the correct paths and restart:

service:
  # Enable HTTPS for the REST and gRPC API
  enable_tls: true

# TLS configuration.
# Required if either service.enable_tls or cluster.p2p.enable_tls is true.
tls:
  # Server certificate chain file
  cert: ./tls/cert.pem

  # Server private key file
  key: ./tls/key.pem

For internal communication when running cluster mode, TLS can be enabled with:

cluster:
  # Configuration of the inter-cluster communication
  p2p:
    # Use TLS for communication between peers
    enable_tls: true

With TLS enabled, you must start using HTTPS connections. For example:

curl -X GET https://localhost:6333

from qdrant_client import QdrantClient

qdrant_client = QdrantClient(
    url="https://localhost",
    port=6333,
)

Certificate rotation is enabled with a default refresh time of one hour. This reloads certificate files every hour while Qdrant is running. This way changed certificates are picked up when they get updated externally. The refresh time can be tuned by changing the tls.cert_ttl setting. You can leave this on, even if you don’t plan to update your certificates. Currently this is only supported for the REST API.

Optionally, you can enable client certificate validation on the server against a local certificate authority. Set the following properties and restart:

service:
  # Check user HTTPS client certificate against CA file specified in tls config
  verify_https_client_certificate: false

# TLS configuration.
# Required if either service.enable_tls or cluster.p2p.enable_tls is true.
tls:
  # Certificate authority certificate file.
  # This certificate will be used to validate the certificates
  # presented by other nodes during inter-cluster communication.
  #
  # If verify_https_client_certificate is true, it will verify
  # HTTPS client certificate
  #
  # Required if cluster.p2p.enable_tls is true.
  ca_cert: ./tls/cacert.pem
