     edt_password.setError("Field is empty!");
   }
   
   // Check password string to be of minimum length of 8 characters and should have
   // atleast 1 digit, 1 upppercase letter and 1 special character
   if (validateTor.isAtleastLength(str, 8)
       && validateTor.hasAtleastOneDigit(str)
       && validateTor.hasAtleastOneUppercaseCharacter(str)
       && validateTor.hasAtleastOneSpecialCharacter(str)) {
   
       // Valid Password
   
   } else {
      // Invalid Password, handle in ui
       edt_password.setError("Password needs to be of minimum length of 8 characters and should have " +
