Authentication

Graphmind supports two authentication modes: token-based and username/password. Authentication is disabled by default — enable it when deploying to production.

Enabling Authentication​

Set an admin user during startup:

GRAPHMIND_ADMIN_USER=admin GRAPHMIND_ADMIN_PASSWORD=secret graphmind

Or with Docker:

docker run -d -p 6379:6379 -p 8080:8080 \
  -e GRAPHMIND_ADMIN_USER=admin \
  -e GRAPHMIND_ADMIN_PASSWORD=secret \
  fabischk/graphmind:latest

Token-Based (Simple)​

For scripts and CI/CD, set a single token:

GRAPHMIND_AUTH_TOKEN=my-secret-token graphmind

Combined​

Both can be used together:

GRAPHMIND_ADMIN_USER=admin GRAPHMIND_ADMIN_PASSWORD=secret \
GRAPHMIND_AUTH_TOKEN=api-token-for-scripts \
graphmind

Roles​

RoleReadWriteAdmin
AdminYesYesYes (manage users, delete graphs)
ReadWriteYesYesNo
ReadOnlyYesNoNo

The initial user created via GRAPHMIND_ADMIN_USER is always an Admin.

Using Authentication​

HTTP API — Basic Auth​

curl -u admin:secret -X POST http://localhost:8080/api/query \
  -H 'Content-Type: application/json' \
  -d '{"query": "MATCH (n) RETURN count(n)"}'

HTTP API — Bearer Token​

curl -X POST http://localhost:8080/api/query \
  -H 'Authorization: Bearer my-secret-token' \
  -H 'Content-Type: application/json' \
  -d '{"query": "MATCH (n) RETURN count(n)"}'

HTTP API — Login Endpoint​

For sessions, use the login endpoint:

curl -X POST http://localhost:8080/api/auth/login \
  -H 'Content-Type: application/json' \
  -d '{"username": "admin", "password": "secret"}'

Response:

{"authenticated": true, "role": "Admin", "username": "admin"}

RESP Protocol​

Single-arg (token):

redis-cli -p 6379
127.0.0.1:6379> AUTH my-secret-token
OK

Two-arg (username/password):

127.0.0.1:6379> AUTH admin secret
OK
127.0.0.1:6379> GRAPH.QUERY default "MATCH (n) RETURN count(n)"

Web Visualizer​

When auth is enabled, the UI shows a login screen on first load:

  1. Enter the server URL (default: http://localhost:8080)
  2. Enter username and password
  3. Click Connect
  4. Credentials are stored in the browser for subsequent requests

If auth is not enabled, click Skip to connect directly.

Python SDK​

from graphmind import GraphmindClient

# Username/password
client = GraphmindClient.connect("http://localhost:8080",
    username="admin", password="secret")

# Or token
client = GraphmindClient.connect("http://localhost:8080",
    token="my-secret-token")

TypeScript SDK​

import { GraphmindClient } from "graphmind-sdk";

const client = new GraphmindClient({
  url: "http://localhost:8080",
  token: "my-secret-token",  // or use Basic auth
});

Rust SDK​

use graphmind_sdk::RemoteClient;

let client = RemoteClient::new("http://localhost:8080")
    .with_token("my-secret-token");

Managing Users​

List Users (Admin only)​

curl -u admin:secret http://localhost:8080/api/auth/users
[["admin", "Admin"]]

Create Users (Admin only)​

curl -u admin:secret -X POST http://localhost:8080/api/auth/users \
  -H 'Content-Type: application/json' \
  -d '{"username": "analyst", "password": "pass123", "role": "ReadOnly"}'

Roles: Admin, ReadWrite, ReadOnly.

Security Notes​

  • Passwords are hashed before storage (not stored in plaintext)
  • Use TLS in production (reverse proxy with nginx or Caddy) to encrypt credentials in transit
  • When auth is disabled (default), all requests are accepted without credentials
  • The GRAPHMIND_AUTH_TOKEN and GRAPHMIND_ADMIN_USER environment variables activate auth on startup
