# Sign in to Your Account

You must sign in using your LF account credentials to access the Linux Foundation's tools. If you already have an LF account, use your credentials to sign in. If you just [created a new account](/lfx/sso/create-an-account.md), follow these steps:

1. Enter your SSO account credentials on the Sign-In window and click **SIGN IN**.

2. The Single Sign-On service allows users to authenticate with social and external authentication providers instead of a username and a password.
3. When using an external authentication provider, you will be prompted to create a username if you don't have an existing one.
4. If you create your LF account by signing in with an external authentication provider, the Linux Foundation will map your LF account to the external login.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.linuxfoundation.org/lfx/sso/sign-in.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
