Does the Clef app facilitate logins on mobile browsers?

Yes! Clef authentication works both with desktop and mobile browsers. 

The only difference for mobile-browser logins is that, instead of displaying the Clef Wave, the mobile browser will automatically open the Clef app on your phone and ask you to authenticate (i.e., scan your fingerprint or enter your PIN). Once you authenticate, you are then redirected to the mobile browser automatically where you can continue browsing as a logged in user.
