Matrix password is indeed a very good idea, but NINETOWNS who designed this matrix is a bit silly. Existing programs are 80 sets of figures, each figure 2, each input and three groups of six figures, the number of permutation and combination of this we can own calculations (mainly because I too lazy to count, and permutation and combination calculations had forgotten). Can actually change the existing card can be 160 numbers, each number one, wow gold at most, the location of the edge of the card look at adding some coordinates to change the number of each type into six groups of a total of six figures, in fact, designed well, it would change the current cards do not have to only input interface on the server so that users know to enter an issue which became a number. Both of these methods seems that no difference how many people actually hacking Chaitai Duo, because if the hacking control of your machine, you enter a password every time he can get the card number corresponds to the relationship between the three groups, as He can see through your machine to fill in the group numbers, so can only be counted in calculating the portfolio can not be considered when ordered. The group later changed to 160 although wow gold kaufen he could get six figures correspond to the location and the relationship may be in order would be difficult to get the whole lot. Moreover, she hoped NINETOWNS log in using a password when the card can provide a user last signed the wrong time, and if someone wants to Daohao numberguess immediately if the user will be found, the user may consider for a password card, and if they feel a waste of Money can live for two weeks and then in exchange for the original card, 4 card turns-for-I think hacking would be more depressing. Also see people who are exaggerating the capacity and NINETOWNS Daohao stupidity, saying that password combination more an hour try out, this is not your server NINETOWNS own PC, NINETOWNS though a bit silly nor stupid to let you easily test your password, is certainly N consecutive errors (banks typically 10 times), today you are no longer posted with no examination of the opportunities.
