The Apple Business Manager server token expires after a year or whenever the account that downloaded the token has their password changed. To renew the token, follow the [instructions documented in this FAQ](https://fleetdm.com/docs/using-fleet/faq#how-can-i-renew-my-apple-business-manager-server-token).
## Disk encryption
<meta name="pageOrderInSection" value="1500">
In Fleet, you can turn on disk encryption on your macOS hosts. Apple calls this [FileVault](https://support.apple.com/en-us/HT204837). If turned on, hosts disk encryption keys will be stored in Fleet.
The disk encryption key allows you to unlock a Mac if you forgot login credentials. This key can be accessed by Fleet admin, maintainers, and observers. An event is tracked in the activity feed when a user views the key in Fleet.
### Viewing a disk encryption key
To view the disk encryption key, select a host on the **Hosts** page. On the **Host details** page, select **Actions > Show disk encryption key**.
### Unlock a device using the disk encryption key
1. Restart the device while holding Command + R
2. Open Terminal
3. Unlock the disk encryption key by executing a command similar to:
```
security unlock-keychain <path to the secure copy of the
FileVaultMaster.keychain file>
```
4. Locate the Logical Volume UUID of the encrypted disk by executing:
```
diskutil cs list
```
5. Unlock the encrypted drive with the Logical Volume UUID and disk encryption key by executing a command similar to:
```
diskutil cs unlockVolume <UUID> -recoveryKeychain <path to the secure copy of the FileVaultMaster.keychain file>
```
6. Turn off disk encryption by executing a command similar to:
```
diskutil cs revert <UUID> -recoveryKeychain <path to the secure copy of the FileVaultMaster.keychain file>
```
Once successful, you can reset the account password using the Reset Password utility and recover data by either logging in to the users account or using the command line.
1. Restart the device while pressing Command + R.
2. Open Terminal and launch the Reset Password utility by executing:
```
resetpassword
```
3. Use the Reset Password utility to reset the accounts password.
4. Restart the computer and log in using the new password.

In the case of a cyber attack, it is possible with osquery to gain read access to files on your system. This is not a feature designed for privacy invasion, but rather a means for security teams to locate files on your device that may have been created or affected by a malicious virus.
