Keep in mind that you may not want to store a "plain" password in that file. If you are going to have passwords in the file you may want to use the crypt function to encrypt the password before storing it in the file. You won't be able to decrypt it, but you'll be able to encrypt it after they enter their password and check it against the version in the text file.
