> 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).

Third-party authentication services provide an alternative way for users to sign in and register on your site. This way, they do not need to go through the registration process and create a new username and password for your site. Instead, they can use the same credentials that they already use on a popular site or service (such as Microsoft accounts, Facebook, LinkedIn, Yahoo!, etc.).

Even new users can sign in to your site like this, in which case the system creates a new user account in the database for them. To learn how to manage the data of imported users, see [Managing user accounts created via third-party authentication services](https://docs.kentico.com/k12sp/managing-users/user-registration-and-authentication/configuring-third-party-authentication-services/managing-user-accounts-created-via-third-party-authentication-services.md).
