+    Create a secure login for your scripts without having to include your password

+    1. Choose a password
+    2. Generate a hash code for your chosen password by running program and entering 'gui' as the password
+    3. Type password into the GUI
+    4. Copy and paste hash code form GUI into variable named login_password_hash
