Digital Signatures have been around since 1976. They are still the most secure method to claim and verify ownership of Internet accounts, photos, videos, code, and any other digital asset. 45 years later, digital signing is rarely used on consumer-facing products and services. They are still too technical, too complicated, and too difficult for 99% of users.
UNS Digital Authentication is as easy as 1, 2, 3. 
1. Scan a QR code with the camera on your phone and click on the link 
2. Confirm you want to login or register 
3. Verify your identity using your phone’s built in biometric lock or passcode.
UNS is a human-centered computer security solution — requiring no discipline and no mental gymnastics – just a handy smartphone.
