Or, if you wanted to, you could also assign random numbers and characters and save them.

PHP код:

CMD:makeadmin(playerid, params[])  
{ 
    new id, string[128], level, code[5];
    randomString(code, 5);
    if(PlayerInfo[playerid][pAdmin] < 7)  
        return SendClientMessage(playerid, COLOR_BLUE, "You don't have acces to that command.");  
  
    if(sscanf(params, "ii", id, level))  
        return SendClientMessage(playerid, COLOR_RED, "SERVER: /makeadmin [ID] [LEVEL]");  
         
    //ShowPlayerDialog(id,DIALOG_ADMINBOX,DIALOG_STYLE_MSGBOX, "You are an admin", string, "Ok", "");  
    format(string, sizeof(string), "%s promoted you to level %i.", PlayerName(playerid), level);  
    SendClientMessage(id, COLOR_BLUE, string);  
    PlayerInfo[id][pAdmin] = level;  
    PlayerInfo[id][pCode] = code; // Assigns the random 5 character code to the player variable
    return 1;  
}
PlayerName(playerid) 
{ 
    new name[21]; 
    GetPlayerName(playerid, name, sizeof(name)); 
    return name; 
}  
randomString(strDest[], strLen = 10) // ( https://sampforum.blast.hk/showthread.ph...pid1349155 )
{
    while(strLen--)
        strDest[strLen] = random(2) ? (random(26) + (random(2) ? 'a' : 'A')) : (random(10) + '0');
}
/*
    And inside of admin commands you can do shit like
    if(!PlayerInfo[playerid][pUsedCode]) return Errormessage..
*/ 


Add pCode, and pUsedCode (or whatever) inside of your PlayerInfo enum, and add it to saving it, and loading it. as a string. All you have to do is work out the login command and/or dialog.

You can do it however you like, but that's similar how I would do it.
