Security Settings Reference Guide

Archive password

File:CrashPlan/Latest/CrashPlan_App_Reference/Security_Overview_&_Settings/set-archive-key-password.png

Item		Description
a	Archive password	Create an archive key password. Re-enter the archive key password in the second password field. Your password must be at least 8 characters and can include any combination of capital (A-Z) letters, numeric (0-9) characters, symbols, and spaces.
b	Question (versions 3.6.1 and later)	(Optional) Enter an archive question for recovering a forgotten archive key password. This can be used to reset the archive key password in the event that you lost or forgot the password. If an archive question and answer is not entered, then the archive key password cannot be reset if it is forgotten or lost. The question is limited to 128 characters.
c	Answer	If an archive question is entered, provide the answer.

Archive question
An archive question reduces the risk of not being able to restore your files due to a lost or forgotten password. However, it increases the risk of someone bypassing your archive key password. If you choose to use this optional feature, take great care when selecting an archive question and answer. In general, a secure question has the following characteristics:

Question has hundreds, if not thousands, of possible answers
Question is not a question you would answer publicly (online or in person)
Answer is easy for you to remember
Answer cannot be researched online via Google, Facebook, LinkedIn, etc.
Answer does not change over time
