Do I have to go through Secure Sign On enrollment with every computer or personal device I use?
You enroll in Secure Sign On only once. It is based on your access ID and password, and not per the computer or device you use to access your accounts. You may be required to validate your identity when you use a different computer or device. You will be presented with the option to use your telephone in conjunction with a security code or by answering a dynamically generated set of questions.
