   I am writing a program that need users to input a password. Users will allow to create their password the first time they use the program. Then the password will be encrypted and store into a text file. But my problem is what if some guys deleted the text file that stored the password, then the program will assume it is the first time being used and asked for new password again. What is a good way to avoid this? Or another way of storing password.

   Thank you in advance!
