This article details how to recover a forgotten/lost passphrase for a PGP Whole Disk Encrypted computer.
Beginning with PGP Desktop 10, PGP Whole Disk Encrypted system users can locally recover forgotten or lost passphrases by entering answers to security questions on the PGP BootGuard screen. These security questions are created when creating a passphrase user during encryption of your disk.
Before you can use local PGP Whole Disk Encryption passphrase recovery feature, you must create your security questions. You can customize the five security questions so that the answers are something that only you would know.
If you then forget your passphrase, you can reset your passphrase by correctly answering three of the five security questions you created when you set up your passphrase user.
In PGP Universal Server managed environments, this feature allows users to recovery their passphrase locally without needing to contact an administrator to use a Whole Disk Recovery Token (WDRT) to recover their passphrase.
