To ensure that Clef can continue to provide secure two-factor to all WordPress users for free, we display a small, non-tracking ad below the Clef Wave. Our carefully curated ads are for WordPress services we love and recommend to our customers.
You can remove the ad forever either with a small, one-time fee or by enabling the Clef badge in your site’s footer.
Yes. As long as your users register on their Clef mobile apps using the same email address as their WordPress accounts, they can start using Clef instantly.
Also, Clef makes it easy to invite your users with optional invitation emails.
See the guide for accommodating users without smartphones for details.
You can add the Clef Wave or the Clef “login with your phone” button by inserting the clef_render_login_button shortcode into any post, page, or text widget. See the shortcode guide for details.
If you have a subdirectory network, then no additional configuration is required.
If you have a subdomain or full domain network, then you must configure the application domain setting to allow Clef logins at multiple subdomains or domains.
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 mobile app.
When configured to disable passwords, Clef protects WordPress users against the full spectrum of password-based attacks:
Clef’s security architecture is fully distributed, which means Clef stores no user credentials on its servers. When you use the Clef mobile app, you create a profile and a private encryption key that never leave your phone. The Clef app then uses that data to generate a unique, encrypted digital signature every time you log in. Since all of your personal info stays on your phone, nothing in the Clef database can compromise your identity even in the unlikely event that the server is hacked.
