hi. 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!

As I move sites to SSL, the need for an out of channel login for use on shared WiFi
is somewhat reduced. The best thing is that Clef allows me make clients who cannot
remember passwords happy. I show them how i just point my phone at the site and 
it’s magic!

Very cool wavy effect and it just works. Now I have secure 2FA login mechanism for
my personal Wordpress site.

If the plugin works in your WP installation… fine, everyone is happy. If by any 
chance, you have a problem with Clef, their support is simply non-existing. You 
are on your own. Check the support page and see how many posts are unanswered.

CPU load average 5%. Enable Clef, 2FA… CPU usage 30-40 % of the whole dedicated 
unit and receiving warning emails from hosting provider saying that its being throttled
dont even bother. Plus people can still access the wp-login.php page anyway, infact
I received more hits and attempted logins via wp-login.php when Clef was enabled
than I have all day when it was not installed…. probably uses all the CPU because
its showing that stupid wave to every single tom dick and harry that wants to visit
the login page and try and get in

It works great, except it seems that it is very hungry in terms of server resources.
I end up with a 500 error too often when I activate Clef. I finally decided to stop
using it. on a shared hosting, I think it’s better not using it. I will look for
an alternative for now.
