Enabling 2FA not only turns it on for the website, it also turned it on for the in-game client.
I found this a bit annoying, so I went to the website to disable it again. After disabling, I can no longer login to my account. It just keeps saying "Invalid token".
I had to re-enable 2FA to be able to login to the game.
Steps to reproduce:
- Enable 2FA on the website
- Open the Medivia client
- Login to the game (notice it prompts you for the authenticator code)
- Close the Medivia client
- Disable 2FA on the website
- Open the Medivia client
- Login to the game and try to connect to any character. It should say "invalid token".
