CSI file download without ePortal login : Is this possible ?

I download CSI from eportal with my login (TAN-based) for my TDS efilling. Is it possible for someone to download it without my login details  ? Keep in mind, I use axis bank, challans of which are not accessible through nsdl.

Please do tell even if there is some totally other way like through bank website or TRACES. 

Thanks in advance !
