When used in a multiclient-server configuration, it allows the server to release an authentication certificate for every client, using signature and Certificate authority. OpenVPN allows peers to authenticate each other using a pre-shared secret key, certificates, or username/password. It is capable of traversing network address translators (NATs) and firewalls. It uses a custom security protocol that utilizes SSL/TLS for key exchange.
