Thanks ...butIs storing password in a file a good option without encrypting it? If someone opens the file, he/ she can read the password.

Hi,You should either encrypt the passwords, or store a hash of the passwords. It depends on if you need to be able to read and use the password, or if you only need to be able to verify that a password is correct or not./Kaj
