UTunnel uses username/password authentication only for the dashboard and client application sign-in process by default. It uses certificate-based authentication which is transparent to the user for VPN connections.
The authenticated session enables username/password authentication for VPN connections too, in addition to the certificate-based authentication. But the user will not see an authentication screen when connecting VPN as an encrypted cached password is used for the authentication. If multi-factor authentication is enabled, the user will need to enter the token on any connection attempt.
