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

## Answer

### Lock / Unlock

**Lock** - Locking a client binds that client to the current model number. Meaning that if something unexpected should happen during a migration or update, a connecting client ignores any new manifests from the server (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 a device to be updated to the latest model.

### Lock Device

Lock the actual screen of the device. The user will be unable to use the device till a passcode (if present) is entered.

## ADDITIONAL INFORMATION

When you lock a device the kiosk will not be available to the user. It will open, but display a message to the user they they are blocked.

Locked device shows a lock icon or text in the client view, device info, and client monitor:
