# Configuration

Language, backup, connection and the My Lockers list.

The **Settings** tab groups everything that is not an account.

## What you need

* The Vault, unlocked.

### The four groups

* **Connection** — [Extension Sync](/vault/sync-with-the-extension.md).
* **Backup** — [Export to QR](/vault/export-a-qr-backup.md).
* **Security** — [Security Settings](/vault/security-settings.md), [Master Password](/vault/change-the-master-password.md), **My Lockers**.
* **Application** — language, **Terms of Use**, and the version of the Vault (currently **2.4.0**).
  {% endstep %}

{% step %}

### Language

Tap the language row and pick from the list. The Vault speaks 16 languages. The terms stay in English.

{% endstep %}

{% step %}

### My Lockers (advanced)

This list is for people who deployed their own Locker Protocol contracts. The Vault knows the official contracts; any other **Locker** or **Launch factory** raises an *unknown contract* warning at signing time. Registering an address here (with your password) turns that warning off for it. **Check the address character by character first.**

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://doc.lockerprotocol.com/vault/configuration.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.
