vRealize Automation uses security passphrases for database security. A passphrase is a series of words used to create a phrase that generates the encryption key that protects data while at rest in the database.

Follow these guidelines when creating a security passphrase for the first time.
Use the same passphrase across the entire installation to ensure that each component has the same encryption key.

Memorize the passphrase or keep it in a safe place. The passphrase is required to restore database information in the event of a system failure. Without the passphrase, you cannot restore successfully.
