CHANGES

18/05/2019 version 0.3
  Accounts saved in keyring. Because it does not unlock keyring when search for accounts (I researched without success), I need to create
  the same empty password every time the application launch.
  I also think that is a bug in libsecret: https://gitlab.gnome.org/GNOME/libsecret/issues/7
  Removed GtkViewPort (not necessary).

27/04/2019 version 0.2
  Updated to fix issue that menu bar, toolbar and status_bar change size if you change window size. Fixed with property vexpand to FALSE.
  Now the account buttons are inside a GtkScrolledWindow (that needs a child GtkViewport to add a container),
    so you can resize the window and scroll to view any button.
  Now I use GtkBox in both containers because is not necessary a GtkGrid.
  Increased maximum number of accounts to 1000.
  Removed gtk_widget_show for each widget because the window has gtk_widget_show_all (window).

22/04/2019 version 0.1
  Fork from google-authentication-libpam developed with GTK+ 3.24.8 in Archlinux to learn to develop GTK+ applications.

  You can create accounts with name and key (max. 16 chars).
  It has GtkWidgets menu, tool bar and status bar.
  Created typedef struct MYDATA to pass several GtkWidgets in signals.

  If you can not get this version, you can try to change the line to check version in configure.ac:

    AM_PATH_GTK_3_0(3.24.8..

  and change the calls in src/gauthenticator.c that return error for previous versions calls.

  You can add up to 5 accounts with the menu option or the add button in tool bar (only for debug. In final release I can set up to any number).
  Each time a button with the account name will be created. Every time that user press button, the code will appear in the status bar.
  If user press copy button in tool bar, the code will be copied in the clipboard.
  After install you can run the program pressing windows key in gnome and typing gauthenticator.
