To enhance the security of e-Way Bill/e-Invoice System, NIC is introducing 2- Factor Authentication for logging in to e-Way Bill/e-Invoice system. In addition to username and password, OTP will also be authenticated for login.
There are 3 different ways of receiving the OTP. You may enter any of the OTP and login to system. The various modes of generating OTP are explained below:
Registration for 2-Factor Authentication:
On logging to e-Waybill System go to Main Menu 2 Factor Authentication and confirm the registration. Once confirmed, the system will ask OTP alongwith username and password. The OTP authentication is based on individual user accounts. The sub users of GSTIN will have separate authentication depending on their registered mobile number in the e-Way Bill/ e- Invoice System. Once you have registered for 2 Factor authentication, then the same is applicable for both e-Way bill and e-Invoice system.
