Rublon, the cryptographic login system that eliminates passwords has published an API for their secure QR Code enabled login. Rublon’s system uses cryptographic methods (asymmetric 2048-bit RSA keys) and secure encryption algorithms (AES 256-bit) but no passwords. It is two-factor authentication without the need for any specialised device like an electronic card or token but it simply transforms the users smartphone into a private key (video below). The free API is available to web developers and website owners and there are already plugins for popular online community platforms and WordPress. There is also direct access to the REST API so Rublon may be serviced by websites based on any programming language.
