I opened a support ticket on a problem with OpenVPN that I’m having. Support replied back that they needed my openVPN credentials and permission to Remote Assist. Thinking that their ticketing system was secure, I provided the credentials.
About 5 minutes later I received an email of the support ticket - the entire thread - that included my username and password credentials for OpenVPN.
I contacted my VPN provider, who had to re-create a new set of credentials - which means I had to go back and touch each of my devices.
Know that anything you enter into the support ticketing system will be sent out over the Internet via email.
