AuthSecured

by touchfalls

AuthSecured brings password login to Minecraft dedicated servers, running as a Fabric mod or as a Paper and Purpur plugin.

FabricMIT LicenseOpen source1.20 – 26.2

What it does

Players set a password and must authenticate before they can play on a server running AuthSecured. Passwords are stored as Argon2id hashes, and the data can be kept in SQLite or PostgreSQL. Redis handles local rate limiting, so repeated failed attempts are throttled. Restrictions apply before authentication, and an authentication timeout limits how long a player can stay unlogged. Reconnect sessions are optional and can let a returning player skip the login for a set period.

The mod ships with English, Russian, Spanish, Italian and French messages. Server owners get admin commands for status checks, a doctor command, an audit log, granular permissions and temporary password resets. Players use register, login, changepassword, logout and authstatus. The project is open source and released under the MIT License, with files for 1.20 – 26.2.

Fabric servers take the JAR whose suffix matches the server version, alongside the Fabric API for that version. Paper and Purpur take the Paper JAR in the plugins folder. Older historical releases have different compatibility, so one server should run one platform artifact.

Key features

  1. Password authentication

    Players register a password and log in before the server lets them move or act.

  2. Hashing and storage

    Passwords are kept as Argon2id hashes, with SQLite or PostgreSQL as the storage backend.

  3. Pre-login restrictions

    Restrictions and an authentication timeout apply until a player has logged in.

  4. Admin tooling

    Status, doctor and audit commands, granular permissions and temporary password resets help server owners manage accounts.

Questions

Does AuthSecured need Fabric API on Fabric servers?

Yes. The matching Fabric API must be installed next to the Fabric JAR whose suffix matches the server version.

Can AuthSecured run on Paper or Purpur?

Yes. Paper and Purpur use the Paper JAR as a plugin, and a server should run only one platform artifact.

Which Java version does AuthSecured need?

Minecraft 1.21.x needs Java 21, while 26.x needs Java 25, so check the Java version before installing.
