Two identical strings do not enter the bet

[Saeidsm1]

Hi friends, I need help, please help.
I read a password from a text file and put it in a string to be the main password.
Then I want to enter the password from the input of the monitor serial.
But when I compare them, even though the strings are the same. Does not enter the condition.
How do I make an equal condition?

Code:

#include <SD.h>
File M_Pass;
String Password_From_SD="";
void setup() {
  Serial.begin(115200);
  SD.begin(10);
  Get_str_From_SD();
}
void loop() {
   Menu();
}
void Menu(){
  String Enter_Password_Serial="";
  Serial.println("Enter Password:");
  while (!Serial.available());
  Enter_Password_Serial = Serial.readString();
  Serial.print("Enter_Password_Serial:");
  Serial.println(Enter_Password_Serial);
  Serial.print("Password_From_SD:");
  Serial.println(Password_From_SD);
  if(Enter_Password_Serial==Password_From_SD){
    int buttom_menu=0;
    Serial.println("request number:");
    Serial.println("1.Something");
    Serial.println("2.Something");
  }
  else{
    Serial.println("Password incorrect");
  }
}
void Get_str_From_SD(){
  M_Pass=SD.open("PM.txt");
  char character;
  while (M_Pass.available())
  {
    character = M_Pass.read();
    Password_From_SD += character;
  }
}

I heard strings have "end of string" symbol at the end of string.
Inputs from Serial Monitor window have "New Line" and "Carriage Return" symbols at the end.

In the wokwi, to which you could have "shared" a link BTW, check the documentation for the serial monitor, where you can change the line ending, just like you might in the serial monitor window in the IDE.

Thank you very much, I fixed it with your help by setting the monitor serial in the IDE on (No line ending).
