# What is FileVault?

FileVault is a disk encryption program available in macOS, designed to protect data by encrypting the entire drive.

* Recovery Key: Generates a recovery key that can be used to unlock the disk if the password is forgotten.
* Institutional Recovery Key: Organizations can create and manage an institutional recovery key for IT admin access.
* Automatic Encryption: Once enabled, encryption occurs in the background as you use your Mac, without impacting performance.

## Benefits of Using FileVault
