 ### Authentication
 
-Your [Langflow deployment's authentication settings](/configuration-authentication) determine whether Langflow API requests require explicit authentication with a Langflow API key.
+As of Langflow v1.5, all API requests require a Langflow API key, even when `AUTO_LOGIN` is enabled.
+
+The only exceptions are the MCP endpoints at `/v1/mcp`, `/v1/mcp-projects`, and `/v2/mcp`.
+These endpoints don't require authentication, regardless of the `AUTO_LOGIN` setting.
 
-If explicit authentication is required, you must provide a valid Langflow API key in either an `x-api-key` header or query parameter.
+You must provide a valid Langflow API key in either an `x-api-key` header or a query parameter.
 For more information, see [API keys](/configuration-api-keys).
 
-Because authentication isn't always required, Langflow API examples in the Langflow documentation often omit authentication.
+<details closed>
+<summary>Auto-login and API key authentication in earlier Langflow versions</summary>
+
+Prior to Langflow v1.5, when `AUTO_LOGIN` was enabled with `AUTO_LOGIN=true`, Langflow automatically logged users in as a superuser without requiring authentication, and API requests could 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.
+
+</details>
 
 As with any API, follow industry best practices for storing and referencing sensitive credentials.
 For example, you can [set environment variables](#set-environment-variables) for your API keys, and then reference those environment variables in your API requests.

-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`.

+
+* If `AUTO_LOGIN` is `FALSE`, you must be logged in as a superuser.
+* If `AUTO LOGIN` is `TRUE`, you're already logged in as superuser.
+
+To create an API key for a user from the CLI, do the following:

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

+
+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`, authentication will be skipped entirely, and API requests will not require a Langflow API key, regardless of the `AUTO_LOGIN` setting.
+
+</details>
 
 Langflow **does not** allow users to have simultaneous or shared access to flows.
 If `AUTO_LOGIN` is enabled and user management is disabled (`LANGFLOW_NEW_USER_IS_ACTIVE=true`), users can access the same environment, but it is not password protected. If two users access the same flow, Langflow saves only the work of the last user to save.
