What is a passcode or passphrase?
This is the security code that you create when you retrieve your hardware-based certificate. We recommend that the passcode or passphrase be at least 6 characters in length, and it may be as long as 20 characters. It can consist of letters, numbers, and/or special characters.
The passphrase is case-sensitive (UPPER CASE and lower case letters are not the same thing). You will use this passcode or passphrase each time you access the certificate on your smart card or USB token.
