Two Factor Authentication now supports 1.20 and 1.21!
After quite some time without any updates, the awesome @Nogame1234 refactored some of the codebase, updated dependencies and much more!

Changes

• The plugin now supports 1.8 - 1.21 Minecraft versions.
• The plugin now depends on Java 17 and would only work on servers using any version equal to or above.
• The plugin now uses Atlassian's OneTime library for handling 2FA, replacing the old Google-based library.
• The plugin generates QR codes itself instead of depending on external services.
• Some known bugs related to authentication are now fixed.
