Goodbye Passwords, Hello Login Freedom: Identity Startup Clef Leaps Out of Private Beta to Disrupt Online Authentication With the Release of the Clef Identity Architect

Share Article

Turning passwords into unique visual patterns on your smart-phone, Clef leads the way in bringing military-grade login cryptography to the consumer market.

Today, San Francisco based identity startup Clef has officially rolled out of private beta to announce the availability of the company’s signature identity architecture. Clef is a mobile app that replaces the less secure one-factor identity authentication (user name and password) system with a visually dynamic login pattern. Consumers can then access any site within the Clef network with just one-click while no longer having to remember multiple logins, passwords or other personal signifiers.

With the phenomenal growth of consumer Internet, current password authentication standards are no longer a reasonable defense against identity loss via targeted database breaches or “bucket-brigade” hacker attacks. Even large-scale consumer sites like Evernote, Linked In and Yahoo, each with robust defense systems, have suffered security breaches resulting in the loss of millions of dollars and forcing tens of millions of customers to change their login credentials. Yet, our collective digital identities don’t have to be put at risk as military-grade cryptography, which has been protecting our most secure transactions online for years, is now finally available to consumers.

Founded in early 2013, the privately funded Clef is on a mission to replace the antiquated password authentication paradigm with a more comprehensive and secure distributed identity architecture. Clef’s innovative architecture employs a unique combination of paired mobile devices, cloud-based data services and 2048-bit RSA asymmetric key cryptography for maximum identity protection.

“Clef is leveraging the mass adoption of smart-phone technology to make an identity platform for the modern web, by creating a totally new approach to logging securely in online. We've built a mobile app that enables any site to recognize a user based on their personal smart-phone, instead of credentials they have to remember or type,” said Brennen Byrne, CEO of Clef. “Clef puts military grade cryptography in the hands of every user — and it's infinitely more secure then what currently exists for consumers.”

Clef is designed to work on any Android or Apple smartphone. Once the user downloads the app, they simply set up their secure digital profile, which then allows them to send their own personal digital signature to any site they’re logging in to. When a user visits a site that’s integrated with Clef, they click on the “Log In With Your Phone” button to activate the Clef Wave. The Clef Wave’s unique visual pattern signals to the site that the user is trying to log in. By holding their phone up to the computer screen, Clef grabs the user’s identifying information and automatically sends a digital signature to the site activating a new session. Clef completely eliminates the need for consumers to rely the old, less secure standard of login credentials in order to access digital services. This is why since January of 2013, more than 250 sites have integrated with Clef.

Clef’s founding team consists of Chief Executive Officer Brennen Byrne, Chief Technology Officer Mark Hudnall and Jesse Pollak as Chief Product Officer. In addition, Michelle Dennedy who is the Chief Privacy Officer for security giant McAfee, has signed on as a company advisor.
