API keys

-

Langflow provides an API key functionality that allows users to access their individual components and flows without traditional login authentication.

+

You can use Langflow API keys to interact with Langflow programmatically.

+

The API key has the same permissions and access as you do when you launch Langflow. This means your API key can only access your own flows, components, and data. You cannot access other users' resources with your own Langflow API keys. +An API key represents the user who created it. If you create a key as a superuser, then that key will have superuser privileges. +Anyone who has that key can authorize superuser actions through the Langflow API, including user management and flow management.

+

In Langflow versions 1.5 and later, most API requests require a Langflow API key, even when AUTO_LOGIN=true.

+

The only exceptions are the MCP endpoints: /v1/mcp, /v1/mcp-projects, and /v2/mcp. +These endpoints don't require authentication, regardless of the AUTO_LOGIN setting.

+
Auto-login and API key authentication in earlier Langflow versions

If you are running a Langflow version earlier than 1.5, if AUTO_LOGIN=true, Langflow automatically logs users in as a superuser without requiring authentication, and API requests can be made without a Langflow API key.

If you set SKIP_AUTH_AUTO_LOGIN=true and AUTO_LOGIN=true, authentication will be skipped entirely, and API requests will not require a Langflow API key.

    You can generate a Langflow API key with the UI or the CLI.

    The UI-generated key is appropriate for most cases. The CLI-generated key is needed when your Langflow server is running in --backend-only mode.
