Upgrading your CrashPlan security option to use an archive key password adds an additional level of security beyond the default setting. This article outlines the upgrade process and how to optionally add a security question to enable resetting the archive key password.

Before you begin

When you upgrade your encryption key security to the archive key password option, you change how the encryption key is secured, but the encryption key itself doesn't change. Instead of securing the encryption key with your account password, you are choosing to secure the key with an additional password, called an archive key password.

Archive Key Password Considerations
  • An archive key password applies to all computers included on an account. You cannot have separate archive key passwords for separate computers on a single account, such as CrashPlan for Home family plan subscriptions.
  • If you lose or forget your archive key password:
    • With an archive question enabled: You can reset your archive key password by answering your archive question. If you are unable to provide the correct answer, you will be unable to restore your files and you must start over with a new account.
    • Without an archive question enabled: There is no way to reset your archive key password if it is lost or forgotten. You will be unable to restore files and you must start over with a new account.
    • Code42's Customer Champions cannot assist with recovery of an archive key password or your archive question.


You can opt to create an archive question that may be used to reset your archive key password in the event that it is lost or forgotten. 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.

Creating a Strong Archive Question
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
