# Device used to OPERATE an account

Here, the device becomes heavily intertwined with the proxy variable as the amalgamation of your OS, user-agent and cookies all come into play to determine the degree of credence the algorithm views you with. When running a massive operation, you’d want to program your bots to emulate different combinations of said variables to avoid having a link drawn between them. When you’re [Adding Accounts into InstaInfantry,](/chapter-2-using-instainfantry/adding-accounts-into-instainfantry.md) it will automatically assign a completely randomized user agent depending on the sort of device you select: iOS or Android. Keeping them diverse is crucial to maintaining a long-term botting operation without racking up the expenditure column by relentlessly replacing accounts. 

I personally prefer to stick to android since my accounts already have an association to android as their existential variable but you are welcome to switch. This variable has an almost negligible impact on your account longevity so don’t concern yourself too much with what to choose.

## 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.instainfantry.com/chapter-1-philosophy-and-fundamentals/botting-fundamentals/device/device-used-to-operate-an-account.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.
