Dear Neha Ji,
Nice to know that Ncode is giving such facility.
I am one of the Registration Authority for issuing DSCs. I would like to inform you about some facts which you might not know. e-tokens used for storing DSC are special devices. Even the highest authority cannot un-block a token, for security reasons. To be frank, practically it is immpossible.
N CODE is not un-blocking tokens but it formats the token, puts in a defalt password with copy of your DSC in it. It simply means, they are keeping copies of your digital signature with them, which is illegal.
If your signature is mis-used, the forms / returns filed shall be valid in court of law as per IT Act 2000.
If you still think I am wrong, please tell them to tell your password instead of giving a new one!! They will never be able to do so.
