# Locking Devices

## What is it?

![lock-vs-lock.png](https://kb.filewave.com/uploads/images/gallery/2023-06/gUBXgNI3dTf7cUPI-lock-vs-lock.png)Use this article to distinguish **Lock / Unlock** from **Lock Device**. They sound similar, but they control different behavior.

<p class="callout info">The locking behavior is the same for macOS, Windows, iOS, and non-EMM Android.</p>

## Answer

### Lock / Unlock

**Lock** binds a FileWave Client to its current model number. During a migration or update, a locked client ignores new manifests from the server until it is unlocked. See [Upgrading your On-Premise FileWave Server](https://kb.filewave.com/books/filewave-server/page/upgrading-your-on-premise-filewave-server "Upgrading your On-Premise FileWave Server").

**Unlock** allows the device to update to the latest model.

### Lock Device

**Lock Device** locks the device screen. The user cannot use the device again until the required passcode, if present, is entered.

## Additional information

When a client is locked to the current model, Kiosk is not available to the user. Kiosk can still open, but it displays a message that the user is blocked.

A locked client shows a lock icon or lock text in Client View, Device Info, and Client Monitor:
