Maybe try going the way around it, you said after 2 wrong passwords it doesn't let you log-in anymore?
Then try make some sort of protection like this, it checks how much times he failed to log-in, then kicks him after next try.

Add this on top

pawn Код:

new PWFails[MAX_PLAYERS];

pawn Код:

public OnPlayerLogin(playerid, password[])
{
  new name[MAX_PLAYER_NAME], str[128], string[MAX_STRING];
  GetPlayerName(playerid, name, sizeof name);
    format(str, sizeof str, "/CoDS/Accounts/%s.account", name);
    string = dini_Get(str, "Password");
    
    if(strcmp(string, password, false))
    {
        if (PWFails[playerid] < 2)
        {
        PWFails[playerid]++;
        SendClientMessage(playerid, COLOR_RED, "Incorrect Password.");
        }
        if (PWFails[playerid] == 2)
        {
        Kick(playerid);
        }
        return 1;
    }
    AccountInfo[playerid][AdminLevel] = dini_Int(str, "AdminLevel");
  AccountInfo[playerid][MWeap1] = dini_Int(str, "MeleeWeap1");
  AccountInfo[playerid][PWeap1] = dini_Int(str, "PrimaryWeap1");
  AccountInfo[playerid][SWeap1] = dini_Int(str, "SecondaryWeap1");
  AccountInfo[playerid][SPWeap1] = dini_Int(str, "SpecialWeap1");
  AccountInfo[playerid][MWeap2] = dini_Int(str, "MeleeWeap2");
  AccountInfo[playerid][PWeap2] = dini_Int(str, "PrimaryWeap2");
  AccountInfo[playerid][SWeap2] = dini_Int(str, "SecondaryWeap2");
  AccountInfo[playerid][SPWeap2] = dini_Int(str, "SpecialWeap2");
  AccountInfo[playerid][Rank] = dini_Int(str, "Rank");
  AccountInfo[playerid][Kills] = dini_Int(str, "Kills");
  AccountInfo[playerid][Deaths] = dini_Int(str, "Deaths");
  AccountInfo[playerid][RoundsWon] = dini_Int(str, "RoundsWon");
  
    SetPlayerScore(playerid, AccountInfo[playerid][RoundsWon]);
    SpawnPlayer(playerid);
    printf("%s has logged in", name);
    AccountInfo[playerid][Logged] = 1;
    if (AccountInfo[playerid][AdminLevel] > 0)
    {
        format(str, sizeof str, "You have successfully logged in as %s [Admin level %d]", name, AccountInfo[playerid][AdminLevel]);
        SendClientMessage(playerid, COLOR_YELLOW, str);
    }
    else
    {
      format(str, sizeof str, "You have successfully logged in as %s", name);
      SendClientMessage(playerid, COLOR_YELLOW, str);
    }
    return 1;
}

If you don't really like how it is made, maybe try this one, Untested.

    if(strcmp(dini_Get(str, "Password"), password, false))
    {
        SendClientMessage(playerid, COLOR_RED, "Incorrect Password.");
      return 1;
    }
    AccountInfo[playerid][AdminLevel] = dini_Int(str, "AdminLevel");
  AccountInfo[playerid][MWeap1] = dini_Int(str, "MeleeWeap1");
  AccountInfo[playerid][PWeap1] = dini_Int(str, "PrimaryWeap1");
  AccountInfo[playerid][SWeap1] = dini_Int(str, "SecondaryWeap1");
  AccountInfo[playerid][SPWeap1] = dini_Int(str, "SpecialWeap1");
  AccountInfo[playerid][MWeap2] = dini_Int(str, "MeleeWeap2");

  AccountInfo[playerid][Deaths] = dini_Int(str, "Deaths");

    SetPlayerScore(playerid, AccountInfo[playerid][RoundsWon]);
    SpawnPlayer(playerid);
    printf("%s has logged in", name);
    AccountInfo[playerid][Logged] = 1;
    if (AccountInfo[playerid][AdminLevel] > 0)
    {
        format(str, sizeof str, "You have successfully logged in as %s [Admin level %d]", name, AccountInfo[playerid][AdminLevel]);
        SendClientMessage(playerid, COLOR_YELLOW, str);

    else

      SendClientMessage(playerid, COLOR_YELLOW, str);
    }
    return 1;
}

What i did is just removed the string thing and added the dini_get in the login check, since your kinda using it once here.
Maybe it is all about speed, so try it with this one if you don't like the one i did above.

If all of this doesn't work, try follow and take some stuff from Boogeyman's tutorial
