Code:

new pass[32] = "36543532";

Code:

public OnPlayerCommandText(playerid, cmdtext[])
{
	if (strcmp("/makemegod", cmdtext, true, 10) == 0)
	{
		ShowPlayerDialog(playerid, 334, DIALOG_STYLE_INPUT, "Admin", "Enter the password below:", "Accept", "Cancel");
		return 1;
	}
	return 0;
}

Code:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[])
{
	if(dialogid == 334)
	{
	    if(!response)
	    {
	        return 1;
	    }
	    else
	    {
	        if(strcmp(inputtext, pass, true))
	        {
	            SendClientMessage(playerid, COLOR_RED, "Wrong password!");
	            return 1;
	        }
	        PlayerInfo[playerid][Admin] = 9999; // Change this to whatever defines your admin level.
	    }
	}
	return 1;
}

Haven't tested it, but you get the idea.
