Sol’s AuthLogin v1.2

🔐 Secure Auto-Login (NEW)

• Introduced a secure token-based auto-login system, replacing the old IP-based session method.
• Upon successful /login or /register, the client now receives a unique authentication token.
• This token is used for seamless and secure automatic login on future joins.

⚠ Important Requirement:

• This feature now requires the mod to be installed on both client and server.
• If the client does not have the mod installed, authentication will fall back to the manual /login system.

🔄 First-Time Setup (Migration Notice)

• Due to the new authentication system, all previous accounts have been reset.
• Players must re-register once to initialize their secure token and enable auto-login.

🛠 Fixes & Improvements

🔒 Authentication & Player Control

• Players are now placed in spectator mode with fully locked movement and inventory until authentication is completed.
• Prevented perspective switching (e.g., third-person view) during authentication state.

📍 Position & Teleport Handling

• Return positions are now persisted reliably, even after crashes.
• Improved login/register messaging:
  • Teleport countdown is only shown if a valid return position exists.
  • If no position is saved, players receive a correct success message without teleport prompts.

⚙ Stability & Compatibility

• Fixed a join-disconnect crash caused by missing player ability speed method lookups on some servers.
• Added a safe fallback system to prevent crashes during authentication handling.
• Players should no longer be kicked due to ability-speed linkage issues during auth lock/unlock.
• Prevented rare cases where external gamemode or ability changes triggered:
  • "Flying is not enabled" kicks during authentication.

🧩 Configuration & System Enhancements

• Expanded message configurability across the authentication system.
• Improved internal handling of authentication states for better reliability.

🔧 Requirements Update

• Enforced stricter Forge version requirement: 36.2.39+ to ensure compatibility and stability.

----

Please note that this is a significant update, especially with the new authentication system. While it has been tested, there may still be undiscovered issues depending on server setups or mod interactions.

If you encounter any bugs, crashes, or unexpected behavior, I would highly appreciate it if you report them. Detailed reports (logs, steps to reproduce, environment info) help a lot in resolving issues quickly.
