Secure two-factor that people love to use: strong authentication without passwords or tokens; single sign on/off; magical user experience.

I tried Clef by chance because the installation procedure by my hosting service have such option
When I realize what is it all about I am very satisfied because it allows me to authenticate using my mobile phone and forget about my password.
The options in the plugin is not complicated and easy to learn

Thank you Clef

Fantastic plugin. Nice and easy to install / run. Great feature around "recovery URL".

I had to contact support due to an issue I was facing and they were very responsible. Turns out the issue was me, not the plugin. Great team.

Best WP-plugin ever!

Works great - Let's see it on WordPress.com

I use Clef on multiple sites and it works great. I have one very large membership site where members are always having trouble remembering their passwords. Clef enables us to give them an alternative, and it has eliminated that problem for many.
I hope that WordPress.com is seriously considering adopting it. It would be a great service for sites on WordPress.com

so cool

Perfect Plugin

Switching to Hybrid mode has encouraged my continual use in Clef, since some of my client do not have smartphones, making this plugin work for any client I have. The code is solid and I can rest assured that, along with ithemes security and my own clean.php, my site is safe and sound. Thanks Clef! :)

Great Plugin and Support!

We are a WordPress hosting service, http://www.koomohost.com and we have achieved incredible results when we added the Clef Plugin to all of our WP managed sites.

We loved it so much we applied and got approved for their Safer Hosts list!

Not only that, we get geeked out everytime we use the Clef mobile app to login.

Keep up the great work!

Sometimes people come along who just want to improve something and do not look for any commercial gain. It is refreshing to find Clef, so innovative, so new, so ground-breaking, so needed in these days of TOO many passwords and constant reminders about the lack of security on the WWW.

Thank you to Jesse and Mark and all at Clef for making such a great contribution to our daily lives.

Cannot wait for the version upgrade where we can be logged in to more than one computer at a time with Clef. I know they're working on adding support for being logged in to multiple computers at the same time, but it's not quite ready yet. Soon!

Excellent, Secure, Alternative to Passwords
By , for WP 4.0

Clef is really a great alternative to passwords. Couple that with their awesome support its a no brainer. If you're looking for an alternative to passwords and something like a 2 step verification for users logins, Clef would be an excellent choice. Clef's, smartphone to screen connection makes for a totally secure, unique login and saves time, headaches and frustration dealing with lost or compromised passwords. Clef is a great plugin for any WP site — and as a developer a must for any toolset where managing Client logins is a requirement.

Handy and Simple Passwordless Login
By , for WP 4.0

I really enjoy using Clef on the sites I can use it with. It takes the place of two-factor authentication (if you don't have my phone, you aren't getting in), it allows me to remain logged in to all of my Clef-protected sites by just logging in to one of them, and I can control the expiration time of the particular logged in session.

There's definitely quite a bit to love.
