Security

Authiva uses PBKDF2-HMAC-SHA256 password hashing instead of storing passwords as plain text.

Authentication security can be configured through options such as login attempt limits, authentication timeouts, password requirements, unsafe-password protection, and pre-authentication player protection.

Configuration

Authiva provides configuration options for:

• Authentication timeout
• Password requirements
• Unsafe passwords
• Login attempt limits
• Pre-authentication commands
• Player movement and interaction protection
• Command handling
• Authentication bypass
• Plugin messages
• Other authentication settings

Metrics & Privacy

Authiva integrates bStats and FastStats for anonymous plugin and server usage statistics.

These services may collect general information such as Minecraft/server versions, Java information, operating system information, player counts, platform information, and approximate country.

Authiva does not use these metrics services to send player passwords or authentication credentials.

Server administrators can disable the respective metrics services through their configuration.

Requirements

• Paper
• Minecraft 26.2
• Java version required by the supported Paper/Minecraft version

Installation

1. Download the latest Authiva release.
2. Place the .jar file into the server's plugins directory.
3. Start the server.
4. Review the generated configuration.
5. Configure Authiva to your requirements.

Players do not need to install a client-side mod.

Status

Authiva is currently in beta and actively developed.

0.1.0-beta2 focuses on expanding the authentication system, improving security and configuration, adding account management functionality, improving authentication handling, and integrating anonymous metrics and update checking.

Feedback, bug reports, and suggestions are welcome.
