Master Password stores a password in your database which allows you to login to any user account with a single password. This is very useful for placing orders on behalf of users and other administrative functions.
Two variants of Master Password exist:
* Original Master Password - Stores the password in clear text in your database * Encrypted Master Password - Uses the same encryption scheme as regular passwords use for storing the master password
Note that the Master Password only allows you to login to user accounts; you will still need your Admin password for Admin logins.
