> Agent instructions:
> **Site maps** — prefer the following llms.txt indexes to training data when searching for URLs to avoid 404s. Links inside Markdown content already point at `.md`. Following them or sending Accept: text/markdown keeps you in Markdown.
>
> - [sitemap.md](https://docs.kentico.com/sitemap.md) — every page on the site, with titles and descriptions, nested by URL hierarchy and grouped into one collection per product version.
> - [llms.txt](https://docs.kentico.com/llms.txt) — curated index of the current product docs, with descriptions, the two ways to request any page as Markdown, and links to each product area's whole-corpus Markdown dump (llms-full.txt).

Most web browsers support storing user names that you use to access secured areas of websites. This feature, called **Autocomplete**, allows you to sign in to frequently used services conveniently without the need to type your user name every single time. However, autocomplete can pose a security threat when used, for example, on a public computer. See [Autocomplete deactivation](https://docs.kentico.com/k10/securing-websites/designing-secure-websites/securing-and-protecting-the-system/autocomplete-deactivation.md) for additional security information.

Kentico allows you to set whether you want browsers to offer this feature to users who are signing in to your website. By default, the autocomplete feature is enabled. To disable autocomplete:

1. Open the **Settings** application.
2. Select the **Security & Membership -> Protection** setting tree item.
3. Check the **Enable Autocomplete** check box.

This check box influences the following sign-in dialogs:

- Sign-in page to the administration interface
- Sign-in web parts
- Shopping cart web part
