Method and systems for performing biometric registration and authentication of a user, via a user device, over a communication network to provide access to a secure network. The method includes transmitting, via the communication network, non-biometric authentication credentials of the user to initiate a determination of validity of the non-biometric authentication credentials. The method further includes receiving an authentication token based upon the determination of the validity of the non-biometric authentication credentials. The method further includes obtaining biometric information from the user via the user interface and at least one biometric sensor. Biometric data, produced from the biometric information obtained from the user, is sent to an ID server configured to store the biometric data in association with the user. The client app is configured to perform a biometric authentication to provide access to the secure network based on the biometric data stored by the ID server.
