I used a generated OpenVpn configuration file on my iphone before I sold the phone, and stupid I was, I forgot to delete the settings. I am worried that my configuration file and potentially the certificates and key associated with my account are compromised. Is there a way I can disable the previously generated configuration files? I did a little experiment with my new cellphone, trying to reset the password to my account, but it did not affect the configuration file or my cellphone connection. Apparently the configuration file does not include the real password. Any suggestions? What's the worst case scenario if someone else has the file? Thanks in advance for your help.
