When you enable 448-encryption + password archive encryption, you must select an archive key password. The archive key password is required to restore your files. This tutorial describes how to change your archive key password from the CrashPlan app.


  • You must know your existing archive key password in order to change it. The archive key password cannot be reset if you lose or forget it unless you have set an archive question.
