Is it possible to remember a private password in OpenVPN?

Question

openvpn

In order not to enter a login / password when connecting to OpenVPN, it is enough to create a file with two lines and specify the parameter in the config.
auth-user-pass password.txt
But what if a second (private) password is required for authorization? Linux has a Network-Manager that can remember both passwords. And what to do in Windows with its OpenVPN GUI?

Answer 1

I'd rather use KeePass or similar for both, password.txt is obviously safer
