  • When the user chooses to Login, check whether his/her credentials exist in the file or not based on the user input.
  • If it doesn’t exist then ask them to go for Registration.

• Password

  • If they have chosen forget password you should be able to retrieve their original password based on their username provided in the user input (only if their username matches with the data exists in the file).
  • If nothing matches in your file you should ask them to Register. (Since they don't have an account).

File Management
