Highly Recommended!

This is far the best security for wordpress. I would highly recommend it to friends! Thanks for this great software!

Great plugin. Easy to setup and use.

This is a really cool idea. I love logging into my site by just waving my phone in front of the screen. I wish it had the ability to log me in at multiple locations, without having to log out of one, and then log back in on the other. Big time saver though. Thanks!

I am excited about the technology,
I have installed the wp plugin on my site, installed on my cell phone and installed the chrome extension.

Using Chrome I got locked out of my site.

I could get in only by using another browser,

I suspect there is a problem with the chrome extension.

My conclusion:
It is a serious technology leap hence bears a heavy responsibility, I doubt if the current developers understand it.

Great! Except It's Cutoff On Phones

I love this two-factor authentication option. However, the iframe's width is 400px wide which is wider than the iPhone 5/5C/5S screen—320px—and the iPhone 6/6S screen—375px—as well as many other mobile phones out there. And the crazy thing is that they don't need it to be so wide. It's just extra whitespace. You'll have to hack it with CSS positions or negative margins if you want to keep your beautiful responsive website design. Disappointed.

very clever method

Benefit of Security
By , for WP 4.2.4

I love this app, especially after using Wordfence's app and seeing how many brute force attempts I have to log into my site. I used to work for a hosting company, and everyone was super excited with Clef came out, as they should have been. It's a great app and I feel more secure doing it. It's lived up to the hype as far as I'm concerned. I highly recommend it.

High quality; also impressed with their support
By , for WP 4.2.3

Installed and got it working. Works great, the plugin itself feels robust. (I can't vouch for Clef authentication / security itself but I see that it generally gets favorable reviews in the press.)

There were a few technical snags but that was handled in just minutes -- via CHAT! -- with support (from their tutorial page). This really impressed me.

With authentication one big question that arises is, what kind of back door does it provide? If at some point my phone is lost or broken (or if I run into technical problems — which I did), I don't want to be totally locked out of my site. But at the same time, any back door reduces the security of my site. I think the solution they provide is a really good compromise.

All in all, very happy with it!

it was a five star but...
By , for WP 4.2.2

inexplicably it just stopped working for me.
I have TML and Woo on my site. WP 4.2.2 (2015) and Clef was working flawlessly. Loved it, but then suddenly zero. Login would loop. Rescue URL didn't work. I went into to delete the plugin to access my site.

I'm not saying I"m not going to retry this in the future, but for now, it's ready for PROD just yet. I'll stick to Google Recaptcha until i take another crack later.

Otherwise Clef shows lots of promise.

Easy to set up, and just works so well!

Love this App and have it installed on many of my WP sites. I love the 2 level authentication. I'll definitely continue using. Keep up the great work!
