By far one of the best ways to login I have ever seen implemented. Not only that but it makes you feel very futuristic. I was also just impressed with their security feature. I used clef to login on a computer I've nevr used before, it recognized that and had a sweet url verification step. Really digging this app.

By far the best two-factor authentication system I've used imo. Using this as an replacement login system for WordPress is a breeze to configure and removes any chance of malicious access through brute facing of passwords. Given the option I would log into any service I can with Clef.

This tool is simply awesome and easy to use. It makes managing websites easy and more secure. So far it has been stable and the backup website to login using plain old password eases my worry abt being locked out if the clef system is down.

If you have a single site, this is the greatest invention ever. If you have multiple sites however sometimes you have to log out of the site that you're already in in order to be able to log back into a separate site and then the original site you were on. If you manage multiple sites and update them intermittently or simultaneously, it can be a pain. I'm sure they'll fix this in subsequent releases.

LOVE THIS APP! I have yet to find a "big" website to use this (other than WordPress which is how I found out about it), but as a HTML/CSS/jQuery/PHP web developer, it takes the security part out of the worry when creating logins for websites. And it's universal. Once you sign up, your login is good for any websites that use Clef. Can't wait for everyone to discover it and start using it! :)

I spent more time troubleshooting issues and conflicts with other plugins, than improving my WordPress site. I was never able to access my admin back-end via mobile, because I couldn't get a successful Clef login. This app isn't quite ready for live use on WordPress sites. Good Luck Clef, I hope you can work out all your bugs.

Of you maintain several wp sites this tech is great! Saves hours over months of going into keyword vaults to copy and paste ridiculous passwords.

May take a little getting used to, but once you've gotten in the habit of using this app ... other logins seem outdated by comparison. Highly recommended!

Really like logging in with Clef. One of my sites repeatedly logged me out before I installed Clef. Now I can stay logged in as long as I want with no problem. It's very quick and easy to log in initially with Clef each time as well. No more having to remember or type all the different passwords for all my different sites either. Very nice tool.

I chose to secure my new WordPress website with Clef and been using it for a few days now to authenticate in order to add new content. It's so simple and fast to use with my Samsung Galaxy S6, and beats typing in passwords anyday. I heartily recommend it.

Easy to use, faster than typing a password. More secure. What's not to love. Wish I could use this on every site.

some minutes after I rated 5* I received some errors, have been disconnected and now I am waiting for 20 minutes to try login again. Will delet it as soon as possible!!
