(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! ![](https://secure.gravatar.com/avatar/0834bbc8f633be70e8ea506846aa93626588edb8605217aafc645e4ba02e34d7? s=60&d=retro&r=g) ### 󠀁[Secure and good for password-challenged clients](https://wordpress.org/support/topic/secure-and-good-for-password-challenged-clients/)󠁿 [Steven Stern (sterndata)](https://profiles.wordpress.org/sterndata/) 23 februari 2017 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! ![](https://secure.gravatar.com/avatar/8feba0307ec1e3e48b5142ade1cb780f4b7bb149da93e497ecb13920055b723d? s=60&d=retro&r=g) ### 󠀁[Login activities and remote logoff – love those features](https://wordpress.org/support/topic/login-activities-and-remote-logoff-love-those-features/)󠁿 [Dio Phung](https://profiles.wordpress.org/dio/) 20 februari 2017 Very cool wavy effect and it just works. Now I have secure 2FA login mechanism for my personal Wordpress site. ![](https://secure.gravatar.com/avatar/b1e13c3da8ae04685f2bb96baebd5afd11323d915ca183f0f00cbd81a52f9c23? s=60&d=retro&r=g) ### 󠀁[support = 0](https://wordpress.org/support/topic/support-0/)󠁿 [MastroMicio](https://profiles.wordpress.org/mastromicio/) 18 februari 2017 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. ![](https://secure.gravatar.com/avatar/afeba7434c535a9bc5b80edb96ee3665c919009dacd3e1fb719b2bc38adb3638? s=60&d=retro&r=g) ### 󠀁[absolutely will not work on shared hosting without throttling your CPU](https://wordpress.org/support/topic/absolutely-will-not-work-on-shared-hosting-without-throttling-your-cpu/)󠁿 [sumoyoshi](https://profiles.wordpress.org/singlemanstravel/) 13 februari 2017 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 ![](https://secure.gravatar.com/avatar/caf5129eadf891a81fd7899c5f404b816488ebec4db0eb78eed990d1b931a8d0? s=60&d=retro&r=g) ### 󠀁[hungry plugin](https://wordpress.org/support/topic/hungry-plugin/)󠁿 [schawki](https://profiles.wordpress.org/schawki/) 4 februari 2017 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.
