Password-based Authentication: This is the basic authentication mechanism that uses username and password pair. End-users can login to e-Pramaan using the chosen username and password. Additionally, end-users may also provide their Aadhaar number on the self-registration form, this can subsequently be used to login to e-Pramaan.
Aadhaar number and password pair can be used for login in place of username and password pair.
OTP-based Authentication: End-users can prove their identity using an OTP (One Time Password) received on e-mail or mobile. OTP can also be generated using a mobile application offered through e-Pramaan. OTP-based authentication will be in conjunction with any one of the single authentication types.
Digital Certificate (DSC)-based Authentication: End-users will establish their identities using hardware or software tokens (along with PIN). This will be accomplished using tokens in the form of digital certificates/digital signatures/smart cards already in possession of end-users. Hardware tokens can also be in the form of SIM extensions, SD cards, or USB crypto, and will need to comply with CCA guidelines.
Biometric-based Authentication: This is one of the stronger authentication mechanisms provided to end-users. Biometric authentication will be conducted in accordance with Aadhaar authentication process and end-users must possess an Aadhaar number to avail biometric-based authentication.
