SQRL
SQRL or Secure, Quick, Reliable Login (pronounced "squirrel" ) (formerly Secure QR Login) is a draft open standard for secure website login and authentication. The software solution typically uses a QR code, which provides authentication, where a user identifies anonymously rather than providing a user ID and password. This method is thought to be impervious to a brute force password attack or data breach. It shifts the burden of security away from the party requesting the authentication and closer to the operating system implementation of what is possible on the hardware, as well as to the user. SQRL was proposed by Steve Gibson of Gibson Research Corporation in October 2013 as a way to simplify the process of Authentication protocol, without revealing any information about the transaction to a third party.
==Motivation==
The protocol is an answer to a problem of identity fragmentation. It improves on protocols such as OAuth and OpenID by not requiring a third party to broker the transaction, and by not giving a server any secrets to protect, such as username and password.
Additionally, it provides a standard that can be freely used to simplify the login processes available to password manager applications such as LastPass. More importantly the standard is open so no one company can benefit from owning the technology. Such a robust technology should be in the public domain so the security and or the crypto can be verified, and not deliberately restricted for commercial or other reasons.
