+Access to all authorized resources with a single instance of authentication +The elimination of multiple user accounts and passwords for an individual
The mathematical algorithm used by HMAC-based ONE-Time Passwords (HOTP) relies on two types of information to generate a new password based on the previously generated password. Which information is used to generate the new password? (Select two) +Counter +Password +Passphrase +Shared secret +Username
