Definition of recovery password

For BitLocker Drive Encryption, a numerical password that consists of 48 digits divided into 8 groups. Each group of 6 digits is reduced to modulo 11 (a numerical calculation) before being compressed into corresponding 16 bits of passphrase data. A copy of the passphrase data is stored on disk encrypted by the volume master key and thus an administrator can retrieve the recovery password after Windows has loaded. The recovery password must be entered by using the function keys on the keyboard.
