# Basic Authentication Settings

Information on the basic authentication section

Allows you to configure the basic authentication settings for Umbraco. A basic authentication section fully populated with default values can be seen here:

```json
"Umbraco": {
  "CMS": {
    "BasicAuth": {
      "AllowedIPs": [],
      "Enabled": false,
      "RedirectToLoginPage": false,
      "SharedSecret": {
        "HeaderName": "X-Authentication-Shared-Secret",
        "Value": null
      }
    }
  }
}
```

## AllowedIPs

This is a comma-separated list of IP addresses you want to limit where the requests can come from.

## Enabled

If the value is set to `true`, the basic authentication is enabled. By default, the value is set to false.

## RedirectToLoginPage

If the value is set to `true`, instead of showing the basic authentication popup in the browser, the user is redirected to the login page. This is required for external logins to work. By default, the value is set to false.

## SharedSecret

A shared secret can be sent using an HTTP header to bypass the basic authentication. This can be valuable for server-to-server communication.

### HeaderName

The header name used to compare the shared secret. By default, the value is set to `X-Authentication-Shared-Secret`.

### Value

The value of the shared secret. Must be a string longer than 0 characters to be enabled. The default value is `null`.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.umbraco.com/umbraco-cms/13.latest/reference/configuration/basicauthsettings.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
