Clef is a game-changer.

It changes how online security is implemented - and your site is now even more secure.

It changes your smartphone into a fun-to-use two-factor authenticator. Yes, that's right, the phrase "fun-to-use" and "two-factor authenticator" is the very same sentence.

It changes the mindset that online security is too hard - no more excuses for using weak passwords.

Amazing - simply amazing.

If this could be bottled they would have to label it "Awesomesauce". It's that awesome. :)

Safe, Fast, and Easy
By , for WP 4.1.1

I've been using clef on all my WP sites for about a year now. I love how easy it is to setup and once configured logging in has never been so easy. I have been using strong passwords on all my sites and a password "wallet" type app on my phone to help generate strong random passwords and store them so I can log into everything. I hate having to type out these long, complex passwords and scrolling through sites in my phone app so I can log in.

This is more secure and much easier. Clef provides 2 factor authentication, which means I need my phone to log into a site which proves I have my phone and know the pin for clef as well as the password for my phone. It is much more difficult to spoof that and with many phones adding some kind of biometric mechanics it will mean that not only is my phone there, it will mean I'm there after my next phone update.

Even better, I don't have to find the site on the list of sites or try and type in a long random password ever on my WP sites. I scan the wave and I'm logged in automatically. It takes less time than finding the password on any other site without Clef support.

My only complaint is all the sites that haven't embraced the wave.

The Owls are Not What They Seem

This is an excellent two-factor authentication solution for WordPress, and nothing could ever beat free. I use it on my own sites. Thank you Clef!

However, you'll have to know of 2 caveats (free comes at the price):

  1. There's no session control. You can log into all of your Clef-controlled sites (including Facebook, through Chrome extension), but only from one browser. In their own words, "Clef's SSO works on one browser session at a time. Syncing sessions across multiple computers and possibly even multiple browsers is on the development roadmap but likely still a ways off until production."
  2. WordPress version, when installed as a total login replacement, doesn't really replace login form. Oh, it does, but only for us humans. Malicious scripts will continue kicking on your real login form trying to guess your username (admin, of course) and password (watzit, sex? god? 123?))… So by all means, use Clef – but also install a good security system.

PS: Their login window are quite ugly when laid over WP 4.1.*'s default login form, so you'll need some additional styling ;)

Please help me out of this

Clef makes security easy!
By , for WP 4.1

I use Clef with the iOS app. It is a seamless combination.

First of all this plugin is very simple to install. I really like the feature of providing an hidden override URL (in case my phone is not working). Plus the other plugin options are explained well and easy to select.

I also used their recommended security check-list on their blog to further secure my WP install when first setting up my site.

I have emailed their support and found them to be extremely helpful.

This will be a standard plugin on all WordPress installs.

Job well done!

Great Plugin

Nice Concept with a great execution. Simply Superb :)

great way to safely log in
By , for WP 4.1

I recently gave clef a shot on a new WP build and have to say I love it. It relies on having your smartphone available and offers time control for log ins.

My one issue is having clef installed on an additional sites. I am unable to log in to a different site with clef when logged in on another. It could be me, but I have to log out of one to log into the other using the app. It does offer a safe url pass if you want to type pw manually. I would prefer ability to manage multiple logins through app.

But overall happy with app and customer service. The clef team is great.

FINALLY!!! Awesome security for websites
By , for WP 4.1

I have been in the IT industry for over 20 years and until now, there has not been any credible security plugins for what I consider every day users. When I discovered this app I was ECSTATIC!! This plugin offers the same levels of security that large corporations utilize in keeping their intranets safe from the outside world. Since discovering this I have implemented it on all my websites as well as daily logins to places like amazon, ebay, paypal etc. For a free plugin with better than corporate level security is a WIN WIN for us wordpress users!! THANK YOU for finally making my outside endeavours as secure as my corporate ones.
