# Just-in-time Authentication (JIT)

Lithnet Access Manager supports granting access to computers and groups using a simple, just-in-time (JIT) access model.

Rather than administrators having permanent access to computers or groups, they can use Access Manager to grant themselves access on a temporary as-needed basis.

By reducing permanent administrators, you can rapidly increase the difficulty of a successful lateral-movement based attack in your environment.

Access Manager supports two forms of JIT:

* [JIT for Computers](/ams/v3.0/configuration/deploying-features/setting-up-jit/setting-up-jit-for-computers.md) allows you to configure administrators to request just-in-time access to specific machines.
* [JIT for Roles](/ams/v3.0/configuration/deploying-features/setting-up-jit/setting-up-jit-for-roles.md) allows you to define a role, based on an Active Directory group, that users are allowed to request access to on a temporary basis.

## 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.lithnet.io/ams/v3.0/configuration/deploying-features/setting-up-jit.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.
