Identifying and authenticating users based on passive factors determined from sensor data

An apparatus comprising:

• a processor coupled to at least one memory adapted to:
• detect a login form while accessing a web page on a website;
• in response to detecting the login form, attempt to authenticate the user via an alternative passive authentication process;
• and
• in response to a successful authentication of the user by the alternative passive authentication process, automatically respond to the login form with previously stored login credentials for the user.

An article comprising:

• a non-transitory storage medium having instructions stored thereon which, when executed by a processor coupled to at least one memory, cause the processor coupled to the at least one memory to:
• detect a login form while accessing a web page on a website;
• in response to detecting the login form, attempt to authenticate the user via an alternative passive authentication process;
• and
• in response to a successful authentication of the user by the alternative passive authentication process, automatically respond to the login form with previously stored login credentials for the user.
