Can I use the same SecureCode for all of my Charter One cards?
Yes. When you register to MasterCard SecureCode you will select a login and a SecureCode. These will be valid for any of the cards you have registered. You must select a SecureCode between 8-15 characters, which includes at least one number and one letter. You may not use SecureCodes that you have used in the past. We recommend that you select a SecureCode that will be easy for you to remember and difficult for others to guess.
