# \ud83d\udd10 PremiumAuthBypass<\/p>\n
**PremiumAuthBypass** is a Bukkit\/Spigot plugin designed to streamline authentication for premium Minecraft players by allowing automatic login based on trusted IP addresses.<\/p>\n
It integrates with **AuthMe Reloaded** and securely links player accounts to their IPs using AES encryption.<\/p>\n
—<\/p>\n
## \u2728 Features<\/p>\n
– \ud83d\udd13 **Automatic Login**
\n – Instantly logs in players if they connect from a trusted IP.<\/p>\n
– \ud83d\udd17 **Premium Account Verification**
\n – Checks usernames against Mojang API to ensure they are premium accounts.<\/p>\n
– \ud83c\udf10 **IP Linking System**
\n – Players can link their IP to their account for future automatic authentication.<\/p>\n
– \ud83d\udd10 **AES Encryption**
\n – All stored IP addresses are encrypted (AES-128) for security.<\/p>\n
– \u26a1 **Async Operations**
\n – Network requests and file saves are handled asynchronously to avoid server lag.<\/p>\n
– \ud83e\udde0 **Smart AuthMe Integration**
\n – Uses reflection to support multiple versions of AuthMe.<\/p>\n
– \ud83d\udcac **Fully Configurable Messages**
\n – Customize all plugin messages via config.<\/p>\n
—<\/p>\n
## \ud83d\udce6 Requirements<\/p>\n
– Java 8+
\n– Bukkit \/ Spigot \/ Paper server
\n– **AuthMe Reloaded** (recommended for full functionality)<\/p>\n
—<\/p>\n
## \u2699\ufe0f How It Works<\/p>\n
1. When a player joins:
\n – The plugin checks if their IP is already linked.
\n – If yes \u2192 automatic login via AuthMe.<\/p>\n
2. If not linked:
\n – The plugin verifies if the account is **premium**.
\n – Prompts the player to link their IP.<\/p>\n
3. Once linked:
\n – Future logins from that IP are automatic.<\/p>\n

## \ud83d\udd27 Commands<\/p>\n
| Command | Description |
\n|——–|————-|
\n| `\/premium accept` | Link your current IP to your account |
\n| `\/premium revoke` | Remove your current IP |
\n| `\/premium revoke all` | Remove all linked IPs |
\n| `\/premium list` | Show linked IPs (confirmation required) |
\n| `\/premium about` | Show plugin info |<\/p>\n
—<\/p>\n
## \ud83d\udcc1 Configuration Files<\/p>\n
### `config.yml`
\n– Enable\/disable plugin
\n– Customize messages
\n– Control join behavior<\/p>\n
### `linked.yml`
\n– Stores encrypted IPs per player
\n– Automatically managed by the plugin<\/p>\n
—<\/p>\n
## \ud83d\udd12 Security<\/p>\n
– Uses **AES-128 encryption** for IP storage
\n– Fallback to Base64 if encryption fails
\n– No plain IPs stored in files<\/p>\n
—<\/p>\n
## \ud83d\udd04 Compatibility<\/p>\n
The plugin dynamically detects AuthMe API using:
\n– `fr.xephi.authme.api.v3.AuthMeApi`
\n– `fr.xephi.authme.api.API`
\n– Legacy `AuthMe` API<\/p>\n
—<\/p>\n
## \ud83c\udf0d External API<\/p>\n
– Uses Mojang endpoint: https:\/\/api.mojang.com\/users\/profiles\/minecraft\/{username} to verify premium accounts.<\/p>\n
—<\/p>\n
## \u26a0\ufe0f Notes<\/p>\n
– Requires AuthMe to force login players.
\n– Without AuthMe, the plugin still runs but cannot auto-login users.
\n– IP-based login assumes stable player IPs.<\/p>\n
—<\/p>\n
## \ud83e\udde9 Example Use Case<\/p>\n
> A premium player joins your server regularly from the same location.<\/p>\n
\u2714 First login \u2192 manually authenticate
\n\u2714 Accept IP linking via `\/premium accept`
\n\u2714 Next logins \u2192 instant automatic login \ud83d\ude80<\/p>\n","protected":false},"excerpt":{"rendered":"
