For Bitcoin to grow, normal users need access to much better security, so his focus is on making advanced security simpler and easier to use. Clef powers logins on more than 35,000 sites and The New York times described logging in with Clef as “magical” and has been recommended by usability and security experts across industries. It keeps users safe with the same public key cryptography used by Bitcoin wallets and wraps it in a mobile app that makes logging in faster and easier than ever.
