📚 ACCOUNT LOCK SYSTEM

Quick Description

The Account Lock System provides an extra layer of security by allowing players to lock their accounts with a numeric PIN! Once locked, the account cannot be accessed even with the correct login credentials until the PIN is entered. Perfect for preventing account theft, sharing, and unauthorized access.

---

How it works

• Players set a 4-10 digit numeric PIN to lock their account
• Once locked, login is blocked until PIN is entered correctly
• PIN is required in addition to normal account password
• Prevents account theft even if password is compromised
• Optional character name filtering for additional security
• Works automatically on login attempts

---

Main features

• Numeric PIN protection - 4-10 digit code requirement
• Account lock/unlock - Toggle protection on/off
• Name filtering - Block invalid character names (optional)
• UI Account Lock - Easy access and setup

    },
}

Login with locked account

1. Enter normal account/password at login screen
2. System detects account is locked
3. Player accesses the blocked account interface

---

Character name filtering

When FilterName = true, the system checks for invalid character names:

FilterName = true, -- Enable name filtering

Blocked name patterns (examples):

• Special characters: @#$%^&*
• Admin-like names: GM, Admin, Mod
• Offensive words (configurable)
• Empty names or spaces only
• Names with SQL injection attempts

Name validation flow:

1. Player tries to login
2. System checks character name
3. If invalid: Login blocked
4. Message: "Your character name is invalid"
5. Message: "Please go to the web to change it"
6. Player must visit website to rename character

Disable filtering:

FilterName = false, -- No name filtering

---

Message types

1, -- System message (blue text in chat)

Available message types:

• 0 = Center of screen (big announcement)
• 1 = System message [Blue]
• 3 = System message [Red]
• 100 = System white (accepts HTML tags)

Example with different message types:

Account_Locked = {
    "[Account Lock] Account locked",
    "[Account Lock] A conta foi bloqueada",
    "[Account Lock] La cuenta fue bloqueada",
    0, -- Show in center of screen
},

Account_Incorrect_Password = {
    "[Account Lock] Incorrect password",
    "[Account Lock] Senha incorreta",
    "[Account Lock] La contraseña es incorrecta",
    3, -- Red warning message
},

---

Multi-language configuration

Each message supports 3 languages:

Message_Name = {
    "English text",
    "Texto em Português",
    "Texto en Español",
    MessageType,
},

Changing existing messages

-- Original
Account_Locked = {
    "[Account Lock] Account locked",
    "[Account Lock] A conta foi bloqueada",
    "[Account Lock] La cuenta fue bloqueada",
    1,
},

### For administrators:
