Reading file not working?

[Awesomeness]

Ok, so you're given 3 options. 2 is to ask the user for a word or phrase and then it gets converted to morse code and added to a file. The 1st Option is to ask the user for a new word or phrase and then it converts to morse code and checks the file to see if that word or phrase has been added to the file.

So far I have most everything working. The problem is when it checks if the new word has been added and is the same it says that the words do not match even if they do. As I tested it, it seems like it's not reading the file or storing the word in a string. I've been working at it for a while and I can't seem to figure it out. Any help is appreciated.

        {
            cout << "Would you like to test a password, or add a password?" << endl;
            cout << "  1 : for test a password" << endl;

The issue is how you're reading the file contents. The getline() should be the condition test. Consider:

#include <string>
#include <iostream>
#include <fstream>
using namespace std;

void addToFile(const string& fname);
void checkFile(const string& fname);

// Test functions as not provided!!
bool passwordValidation(const string&) { return true; }
string encryptToMorse(const string&str ) { return str; }
void makeTrim(string&) {}

int main()
{
	const string fileName {"masterFile.txt"};

	while (true) {
		int option {};

		//Menu of choices
		do {
			cout << "Would you like to test a password, or add a password?" << endl;
			cout << "  1 : for test a password" << endl;
			cout << "  2 : for add a password" << endl;
			cout << "  3 : to quit" << endl;
			cout << "  >>> ";

			cin >> option;
		} while (option < 1 || option > 3);

		//Checks if there is password
		if (option == 1)
			checkFile(fileName);

		//Adds password
		else if (option == 2)
			addToFile(fileName);

		//Leaves
		else if (option == 3) {
			cout << "Thank you, have a good day." << endl;
			return 0;
		} else {
			// This is an error state, this should never happen.
			cerr << "ERROR invalid option" << endl;
			return 99;
		}

	} // End of the while(true);

   // The program did not leave correctly.
	cerr << "ERROR illegal loop exit." << endl;
	return 100;
}

void addToFile(const string& fname)
{
	ofstream encryptFile(fname, std::ios_base::app);

	if (!encryptFile) {
		cout << "Cannot open file\n";
		return;
	}

	string password;

	cout << "Enter a password to add: ";
	cin.ignore();
	getline(cin, password);

	const auto valid {passwordValidation(password)};	//Takes password and validates it

	if (valid) {
		string encryptedWord {encryptToMorse(password)}; //If validation is good then encrypts the password to the file.

		encryptFile << encryptedWord << '\n';
		cout << "Password Added and Encrypted" << endl;
	}
}

void checkFile(const string& fname)
{
	string password;

	//Password to check
	cout << "Enter a password to check: ";
	cin.ignore();
	getline(cin, password);

	const auto valid {passwordValidation(password)};	//Takes password and validates it

	if (valid) {
		string encryptedWord {encryptToMorse(password)}; //If validation is good then encrypts the password
		ifstream encryptedFile(fname, std::ios_base::app); //Open File

		if (!encryptedFile)
			cout << "File did not open\n";
		else {
			for (string fileWord; getline(encryptedFile, fileWord); ) {
				//cin.ignore();
				//getline(encryptedFile, fileWord);

				//Takes the line from file and stores into string word
				makeTrim(fileWord); //Trims

				if (fileWord == encryptedWord) {	//takes the string from file with the new encrypted password and sees if the same.
					cout << "Password matches\n\n";
					return;
				}
			}

			cout << "Password Does not match\n\n";
			return;
		}
	}

	cout << "The entered password is not acceptable";
