About this Mod

SeamlessLogin

Tired of typing your password every time you join an offline-mode server?
SeamlessLogin detects the login prompt in chat and sends your password automatically — no commands, no copy-pasting.


Features

🔐 Password Manager

Store a password for each server you play on. Open the manager from the
multiplayer screen or with a keybind (default: Numpad +).
Each entry has a name, server address, password, and a per-entry auto-login toggle.

⚡ Auto-Login

When you join a server with a saved password and auto-login enabled,
SeamlessLogin watches the chat for a login prompt and responds automatically.
No input required.

🎲 Password Generator

Generate strong passwords without leaving the game.

  • Password mode — configurable length (8–64), optional capitals, numbers, and special characters
  • Passphrase mode — XKCD-style phrases from a built-in word list, configurable word count (3–8)

🛡️ Security

  • Passwords are encrypted with AES-256-GCM before being written to disk
  • Password reuse detection — warns you when the same password is used across multiple servers
  • Show/hide toggle and clipboard copy for safe password handling

⚙️ Fully Configurable

  • Edit login detection patterns (regex) to match any server's prompt format
  • All settings accessible from the in-game mod config screen
  • Auto-login can be disabled per entry or globally

Frequently Asked Questions

SeamlessLogin server crashes on startup – what to do?

Most common cause: wrong neoforge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.8). You can switch loaders with one click in the panel.

Is SeamlessLogin compatible with neoforge?

SeamlessLogin officially supports neoforge for Minecraft 1.21.8. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with SeamlessLogin – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if SeamlessLogin consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
