Need help in change password

I have a security system which needs a password. So in settings it will change the default password. But when I am changing password even it says password changed after it restarts the display is still in current password, it doesn't display the input password. Hope you can help me. Thanks!

hello I think the problem is here when it clears cpw it goes back to that condition and still displays the current password even after I changed the password. It should display the enter the password I don't where I went wrong

bool checkCurrent(){
  if(cpw.length() < 6 | cpw.length() > 6){
          printConfirm(F("------------------"), F("Password should be"), F("be........"));
          delay(900);
          printConfirm(F("------------------"), F("     6 "),F("character long"));
          delay(900);
          
          clearcpw(cpw);
          return false;

  }
  else if(cpw == dpw){
     cpw = "";
     return true;
 
    }
  else
     printConfirm(F("------------------"),F("Current password"),F("does not match!"));
     delay(500);
     clearcpw(cpw);
     
     return false;
    
 }

Where in your code are the following functions defined?

clearchpw()
deletechpw()
hidechpw()

Where in your code is the new password stored in non-volatile memory?

Post the complete code here. Few people will go to random web sites of unknown provenance just to help someone for free.

OK, back to my previous question:

13

in dpw

"dpw" is just a variable. No variables survive a restart / power cycle. Anything you want saved must be saved in non-volatile memory. Start your Google search with "Arduino EEPROM".

You probably meant '||' (logical OR) instead of '|' (bitwise OR). This mistake is in two places.

printConfirm(), and printMenu() return 'int' but have no 'return' statement.

If 'attempt' is >2 when entering 'check()' you will reach the end of the function without hitting a 'return' statement.
