Authentication using one-time passwords and associated indicia for plural sequences

A method for authenticating a user of an electronic computing device using a one-time password (OTP), comprising:

• receiving, at an authentication server, OTP information comprising an OTP and an OTP identifier, both the OTP and the OTP being associated with a user;
• identifying an OTP associated with the received OTP identifier, the identified OTP being one of a plurality of OTPs assigned to the user, the plurality of OTPs being operable to authenticate the user to access goods or services provided by a single service provider associated with the authentication server;
• determining whether the identified OTP matches the received OTP;
• and
• authenticating the user based on whether or not the identified OTP matches the received OTP.

An authentication server for authenticating a user of an electronic computing device using a one-time password (OTP), comprising:

• a communication interface operable to receive OTP information comprising an OTP and an OTP identifier, both the OTP and the OTP identifier being associated with a user;
• and
• a processor coupled to the communication interface, the processor being operable to:
• identify a plurality of stored OTP identifiers assigned to the user, each OTP identifier being associated with an OTP, the plurality of OTPs being operable to authenticate the user to access goods or services provided by a single service provider associated with the authentication server;
• determine whether the received OTP identifier matches any of the identified OTP identifiers assigned to the user;
• if the received OTP identifier matches one of the identified OTP identifiers assigned to the user, identify the OTP associated with the matched one of the identified OTP identifiers;
• determine whether the identified OTP matches the received OTP;
• and
• authenticate the user based on whether or not the identified OTP matches the received OTP.
