I searched for a specific answer to this question and although there are many answers about VPN encryption, I did not find this specific question answered. Setup as follows:
MyPC -> VPN -> RestaurantISP -> Internet
When I first connect to my VPN service using either the OpenVPN protocol or the app supplied by my VPN provider, does it send the username and password unencrypted or are the credentials sent encrypted?
More specifically, if the RestaurantISP installs a packet sniffer, could they see my login details, like username and password?
