You’ve probably heard that to keep your WordPress site secured, you need to provide a strong password, so why add password-free login to your WordPress?
It’s not actually password-free because Clef is a mobile app that replaces your login details using just your smartphone. When you visit the login page on a Clef-enabled site, it will show you a wave in which the Clef app will scan. When the wave is scanned, the app on your phone sends a digital signature to Clef. Once identified, you can now login to your WordPress site.
If you manage multiple WordPress sites then this will be useful as you don’t need to enter your login details all the time to get to your dashboard. All you need is your smartphone, the Clef app, and you can login to your site, password-free.
