While it works really well, it becomes slowly out of sync with time. I've had this running for a few months now on an AWS workspace and I have to wait for it to click over to the next number before actually entering the auth code into openVPN. When using the microsoft phone authenticator app it never goes out of sync. Not sure how to reset the timer because I really don't want to set up all my accounts in this authenticator again.
