[Solved] username and password check

by


I have abandoned that last program and wrote this from scratch.
For anyone new to C++ that would like to use this, it is licensed under the GNU GPLv2 and can be found in Small-Projects-Cpp on Github. Just download “Userpass.zip” as it is not necessary to clone the entire repository.

#include <iostream>
#include <string>
#include <unistd.h>
#include <termios.h>

getpass() makes the password input show asterisks. Not exactly invisible, but it’s probably the best solution for that.

using namespace std;
string PASSWD;
string getPASS()
{
    termios oldt;
    tcgetattr(STDIN_FILENO, &oldt);
    termios newt = oldt;
    newt.c_lflag &= ~ECHO;
    tcsetattr(STDIN_FILENO, TCSANOW, &newt);
    string PASS;
    cout << "Password: "; cin >> PASS; cout << endl;
    tcsetattr(STDIN_FILENO, TCSANOW, &oldt);
    return PASS;
   }

MENU() has a switch/case menu but it is unrelated so i’m skipping it in the asnwer. You can replace it with whatever funtions you want.

int attempts = 0;
int main()
{

   while (attempts == 3)
   {
      cout << "Too many attempts have been made! Exiting..." << endl; exit(0);
   };
   string USER;
   cout << "Username: "; cin >> USER;

   if (USER == "josh") 
       {   
           if (getPASS() == "hsoj")
       {
        cout << "\nAccess granted!\n" << endl;
        MENU();
       }
           else
       {
           cout << "\nAccess denied!\n" << endl; 
        attempts = attempts + 1;
        main();
       };
   }
   else
   {
      cout << "\nAccess denied!\n" << endl; 
      attempts = attempts + 1;
      main();
   };
   return 0;
}
