Authentication output C++ using caesar cipher

alhanz (34)
Hey guys. I'm making a program which let user to login their details and passwords before enabling them to use it. Caesar Cipher

Their login details are stored in the textfile called "login.txt".

the text contain..

1:admin:jmvrw12345:1
2:user1:dbna12345:1
3:user2:dbna12345:1
4:manager:vjwjpna12345:1


I've done the rest of the stuff but the issue is I'm unable to authenticate the user.
Let's say if he enters correctly it will be a success, he will be able to login.

I've cut the username and password using the delimiter ":"
I'm not very well verse in sstream so kinda confused what to do next.

bool::PCMF::authenticate(string id, string pw){
            
        vector<string> file;
        string line;
        string temp;
        ifstream dataFile("login.text");
       
        User u;
        
        if(dataFile.is_open()){
            
            while(dataFile.good()){
                
                getline(dataFile,line);
               

                vector<string> s = PCMF::separator(line, delimiter);
                u.id = atoi(s[0].c_str());
                u.userName = s[1];
                u.passwordCrypted = s[2];
                u.isEnabled = atoi(s[3].c_str());
                file.push_back(temp);
          
            }//end loop
            
            dataFile.close();
            
        }//end if
        

//Problem for this part
         for(vector<string>::const_iterator i = file.begin(); i != file.end(); i++){
             
             
             }//end loop
            
        }//authenticate


The above shows that the function starts to read the textfile.
Then start to "cut" into different pieces so that the next time I want to authenticate, eg "id == id", it will be easy.

Anyone can help me with the codes for authenticate?

Oh this is wad I found from some other web, trying to do something similar to this but fail..

                }
                iteratorU->numOfWrongAttempts = 0;
                _currentUser = iteratorU.base();
                return true;
            } else {
                iteratorU->numOfWrongAttempts ++;
                if (iteratorU->numOfWrongAttempts >= 3)
                    iteratorU->isEnabled = false;
                return false;
            }
        }
    }
    return false;
}
