How secure is Clef?

Very. Clef leverages the computational power of your smartphone and the proven strengths of distributed, asymmetric cryptography and multi-factor authentication to provide secure WordPress logins in a beautifully simple and easy-to-use package.

How does single sign on with Clef work?

Once you sign in to one WordPress site using Clef, you can sign into all of your Clef-enabled sites with a single click — no more typing and retyping passwords. When you're done managing your site, just hit the "log out" button on your phone and you are automatically signed out of all your WordPress sites.

What happens if I lose my phone?

Simply visit Clef's "lost phone" page to deactivate your phone. Once you've deactivated, you can reactivate on a new device and all of your accounts will transfer over.
