Zeropasswords

Zeropasswords replaced the failing usernames and passwords system with ownership of online identities.

Websites powered by Zeropasswords display their QR codes, similar to how cars display their license plates, for everyone to use to login. Many will scan the QR code of a website, but only the registered users will succeed to login because only they can complete their patented cryptographic process with their smartphones. In trusted environments, like your home or work, you can skip scanning and let your phone log you in from your pocket.
