# Security settings
Auto-lock, password on every action, and the wipe button.
## What you need
* The Vault, unlocked. Open **Settings → Security Settings**.
{% stepper %}
{% step %}
### The settings
The Security Settings screen.
* **Auto-lock Timeout** — how long the Vault waits, with no touch, before locking itself.
* **Require Password for Actions** — ask for the master password when signing or showing keys, even if the Vault is unlocked. Recommended.
* **Lock Application** — lock now.
* **Delete Device Data** — erase every account and setting. Permanent.
{% endstep %}
{% step %}
### Choose the auto-lock delay
Options: **1 Minute**, **5 Minutes**, **15 Minutes**, **30 Minutes**, **1 Hour**, or **Never (Not Recommended)**. A short delay is safer; 5 minutes is a good default.
Auto-lock choices.
{% endstep %}
{% step %}
### Delete Device Data (only if you mean it)
Tap **Delete Device Data**. The Vault asks for your password under **Confirm Data Deletion — This action cannot be undone**. Afterwards the device is empty; you can restore from a secret phrase or a QR backup.
The wipe confirmation.
{% endstep %}
{% endstepper %}
{% hint style="info" %}
Settings are saved as soon as you change them (**Settings saved**). If a setting cannot be saved, the Vault says so and keeps the old value.
{% endhint %}

## 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/security-settings.md?ask=&goal=
```
`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.
