2FA Login Security
Protect your Minecraft server with advanced Two-Factor Authentication (2FA).
This plugin adds an extra layer of security by requiring players to verify their identity using an authenticator app before they can fully access the server. Even if a player's password is compromised, unauthorized users will not be able to log in without the unique authentication code.
Features
- Secure Two-Factor Authentication (2FA)
- Support for authenticator apps such as Authy and Google Authenticator
- Easy player registration and setup
- Protection against unauthorized account access
- Fast and lightweight performance
- Customizable messages and settings
- Staff and player account security
- Compatible with modern Minecraft server versions
How It Works
- A player registers their account.
- The plugin generates a secret key for their authenticator app.
- The player links the key with Authy, Google Authenticator, or another compatible app.
- Every login requires a valid one-time authentication code.
- Only verified players gain full access to the server.
Why Use 2FA?
Passwords alone are no longer enough to keep accounts secure. Two-Factor Authentication significantly reduces the risk of account theft, brute-force attacks, and unauthorized access by requiring a second verification step that only the account owner possesses.
Keep your community safe with reliable, easy-to-use login protection.
