2FA for in-game account with Discord account

[Neejik]

Add a feature where the user can enable a two-factor authentication (2FA) for security reasons.

Also, if needed, the owner can enable 2FA globally for users in config/dashboard.php as a setting, or the user himself can enable it via account settings in dashboard and/or via discord command

Important

Although, the main idea is to make the game notifications through Discord dm more relevant, so this option should NOT be mandatory but highly recommended, maybe show a suggestive popup on screen the first time you log in to the dashboard so that the user has the opportunity to choose an option with many advantages ;)
