There are two(2) sections to our unified .ovpn file:
myPhone.ovpn file and comment (put # at the start) or delete the lines that say auth-user-pass and auth-token-user USER. If you don't, the OpenVPN app on your iOS device will keep asking for a username and password that you don't have.myPhone.ovpn file and add the line below:<ca>
myPhone.ovpn.</ca>
That's it!
As a side note, you can keep or delete the <pkcs12> section in the .ovpn file, it makes no difference either way.
To install the .ovpn unified file, follow the steps here.
This has been tested to work on iOS 26.3.1, OpenVPN 3.7.2 (6402) and IPFire 2.29 Core-Update 200.
