yes the app is good. (not awesome!)
it does what it says!
but no support at all! they said you can use it with shortcode.
1- i wanted to put it in my custom login . php
there is no work for shortcode there! but they didn't help me with a single code !
2 - i've blocked back-end (wp-login/wp-admin/wp-...) for non admins.
it get's you to wp-...
and there's no way to change it!
3 - i used it in my sidebar as a widget.
the button looks ok!
but if you logout, and want to login again, then you will see there is no button.
it will show you a form instead "it seems that you've logged in recently with this account ... " "log in again"
and believe me, its css was a mess!
