Back Up Your Encryption Recovery Key (Mac)

This tool is no longer supported. A new tool is expected in Summer 2023. For more information, please read One-Stop App Streamlines the Device Compliance and Registration Process.

If your computer is encrypted and you forget the password that unlocks your hard drive, you'll need the encryption recovery key to unlock your drive. In most cases, Stanford users have their recovery keys backed up in a secure database by the university. The recovery key  can then be retrieved in MyDevices.

Due to a bug that has now been fixed, some recovery keys that were saved using the Stanford Whole Disk Encryption (SWDE) service cannot be retrieved in MyDevices. You can check to see if any device belonging to you has a key available for retrieval in MyDevices.

If your device is encrypted but your encryption recovery key cannot be retrieved in MyDevices, you can use the Key Escrow Tool to fix the problem. 

Get the Key Escrow Tool

There are two ways to get the tool: you can download it on demand or it may deployed automatically to your computer via BigFix.
