# Sign in page
A signed-in required application need a sign in page for users to login and enter the app. A Sign-In page is automatically created when you create a blank app.
### Customize your sign in page
The default sign-in page usually provides sufficient functionality, but you can customize it as much as you want. Simply edit the page like a normal page. For example, you can add new elements or change the background to better suit your users' needs.
### Delete sign in page
If you want to disable sign-in requirement and delete the sign-in page, refers to [App User Management](/app-builder/app-user-management.md#disable-sign-in-requirment) for instruction.

## 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.acho.io/app-builder/app-user-management/sign-in-page.md?ask=&goal=
```
`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.
