Continued: Can I use two-factor authentication like in Yandex.Money on my website?

Question

Yandex

I already asked this question . Can I use two-factor authentication like in Yandex.Money on my website?
And then I accidentally found a similar patent www.freepatent.ru/patents/2385233
But the author did not provide for the possibility of requesting specific cells from the table, but only the option of reading codes starting from a certain cell in one direction or another.
Is the code request from specific cells (as I suggested earlier and as done in Yandex.Money) a significant difference from the code request for one cell as in this patent, sufficient to consider such an option different from the one patented in this patent?

Answer 1

The answer is found in the first part of the discussion. See the last paragraph in the text of the question Can I use two-factor authentication like in Yandex.Money on my website?

Answer 2

This patent is not valid by idea. Such things under the legislation of the Russian Federation are not patented.
