# Prerequisites & Planning

***

### Network requirements

* **Reachability** to the BlockID tenant and the Auth Server public IP from the end-user machine.
* **Firewall rule** on the Auth Server allowing communication on **port 443** after Auth Server setup.
* **Reachability** to MongoDB from the Auth Server.

### Optional: device firmware upgrades

To upgrade firmware on the 1Key device, ensure reachability to one of the following:

* Keybank server IP: `20.212.64.15`, **or**
* `authx.ensurity.com`

On ports **443** and **30500** (TCP).

### Permissions

* **Administrator permission** for installation on target machines.

### Resources from your vendor

* **1Key Device Template Excel sheet** — used to authorize devices in the Auth Server.
* **1Key devices with unique Keybanks** — Keybanks are loaded onto the devices at manufacturing time. Obtain the loaded Keybank details from the vendor.

### MongoDB

* A **MongoDB connection string**.
* A **service account** with permission to create a database.

## 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.1kosmos.com/authentication/1key-biometric/prerequisites-and-planning.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.
