antecedent

(=>
    (instance ?TF TwoFactorLoggingIn)
    (exists (?DE ?DD)
        (and
            (subProcess ?DE ?TF)
            (instance ?DE DataEntry)

            (not
                (instance ?DD UserName)))))

If X is an instance of two_factor login, then All of the following hold: (1) there exist Y (2) Z such that Y is a subprocess of X (3) Y is an instance of data entry (4) Z is an instance of digital data (5) the object transferred in Y is Z (6) Z is not an instance of computer password (7) Z is not an instance of user name

consequent

(=>
    (and
        (attribute ?AC TwoFactorAuthentication)
        (loggedInDuring ?A ?AC ?T))
    (exists (?TF)
        (and
            (instance ?TF TwoFactorLoggingIn)
            (agent ?TF ?A)
            (accountUsed ?TF ?AC)
            (earlier
                (WhenFn ?TF) ?T))))

If two_factor authentication is an attribute of X and Y is logged_in to X during Z, then there exists W such that W is an instance of two_factor login, Y is an agent of W, the accountUsed in W is X, and the time of existence of W happens earlier than Z
