Systems and methods are provided for establishing an encrypted communication link between a first device and a second device. One exemplary computer-implemented method includes accessing, from a storage, identification information of a user of the first device. The method further includes receiving, at a domain name server, a Domain Name Service (DNS) request from the first device requesting a network address corresponding to a domain name associated with the second device, the domain name being used to establish the encrypted communication link to the second device. The method further includes authenticating the user based on the user identification information, the user identification information including biometric information of the user. The method also includes transmitting network address in response to the DNS request based on a determination that the user has been authenticated at the domain name server using the biometric information of the user. The encrypted communication link between the first device and the second device is established based on the network address.
