SQRL (pronounced "squirrel")[2] or Secure, Quick, Reliable Login (formerly Secure QR Login) is a draftopen standard for secure websitelogin and authentication. The software typically uses a link of the scheme or optionally a QR code, where a user identifies via a pseudonymouszero-knowledge proof 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 without the risk of revelation of information about the transaction to a third party.


The acronym SQRL was coined by Steve Gibson and the protocol drafted, discussed and analyzed in-depth, by himself and a community of Internet securityenthusiasts on the newsgroups and during his weekly podcast, Security Now!, on October 2, 2013. Within two days of the airing of this podcast, the W3C expressed interest in working on the standard.[3]

Google Cloud Platform developers Ian Maddox and Kyle Moschetto mentioned SQRL in their document "Modern Password Security for System Designers".[4]

A thesis on SQRL analyzed and found that "it appears to be an interesting approach, both in terms of the envisioned user experience as well as the underlying cryptography. SQRL is mostly combining well established cryptography in a novel way."[5]


The protocol is an answer to a problem of identityfragmentation. 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. More importantly, the standard is open so no one company can benefit from owning the technology. According to Gibson's website,[2] such a robust technology should be in the public domain so the security and cryptography can be verified, and not deliberately restricted for commercial or other reasons.

Phishing protections[edit]

SQRL has some design-inherent and intentional phishing defenses,[6] but it is mainly intended to be for authentication, not anti-phishing, despite having some anti-phishing properties.[7]

Example use case[edit]

Example of a SQRL-URL / QR-code, which could be clicked, tapped, or scanned for website authentication.

For the protocol to be used on a website, two components are necessary: an implementation, that is part of the web service to which the implementation authenticates, which displays a QR code or specially crafted URL according to the specifications of the protocol, and a browser plugin or a mobile application, which can read this code in order to provide secure authentication.

The SQRL client uses one-way functions and the user's single master password to decrypt a secret master key, from which it generates – in combination with the site domain name and optionally an additional sub-site identifier: e.g., , or – a (sub-)site-specific public/private key pair. It signs the transaction tokens with the private key and gives the public key to the site, so it can verify the encrypted data.

There are no "shared secrets" which a compromise of the site could expose to allow attacks on accounts at other sites. The only thing a successful attacker could get, the public key, would be limited to verifying signatures that are only used at the same site. Even though the user unlocks the master key with a single password, it never leaves the SQRL client; the individual sites do not receive any information from the SQRL process that could be used at any other site.

SQRL implementations[edit]

A number of proof-of-concept implementations have been made for various platforms, including for the server (PHP,[8]Drupal,[9] and C# .NET[10][11]) and for the client (Android,[12][13][14]C# .Net,[10]Java,[15] and Python[16]). There are also various server-end test and debugging sites available.[17][18]

Legal aspects[edit]

Steve Gibson states that SQRL is "open and free, as it should be", and that the solution is "unencumbered by patents".[2] After SQRL brought a lot of attention to QR-code-based authentication mechanisms, the suggested protocol was said by blogger Michael Beiter to have been patented earlier and thus not generally available for royalty-free use.[19][non-primary source needed] The patent in question (not expiring until 2030) was applied for by and granted to Spanish company GMV Soluciones Globales Internet SA (a division of the Madrid-based technology and aerospace corporation GMV Innovating Solutions), between 2008 and 2012 by the patent offices of the United States, the European Union, Spain, and Portugal.[20] Gibson responded: "What those guys are doing as described in that patent is completely different from the way SQRL operates, so there would be no conflict between SQRL and their patent. Superficially, anything that uses a 2D code for authentication seems 'similar' ... and superficially all such solutions are. But the details matter, and the way SQRL operates is entirely different in the details."[21]

Squirrels Research Labs Reveals Intel® FPGAs in Power-Efficient Next Generation Ethereum Mining Accelerators

NORTH CANTON, Ohio, Feb. 19, 2020 (GLOBE NEWSWIRE) -- Squirrels Research Labs (SQRL), a world-leader in blockchain technology, today announced a flagship product in the successful JungleCat line of high-performance blockchain accelerators. With the introduction of two new modules starting at $1349, including 16GB of HBM2 in the highest capacity Intel® Stratix® 10 MX FPGAs, SQRL extends its market leadership in FPGA cryptocurrency mining solutions and customer value.

“We are incredibly excited to launch this product based around Intel’s FPGA technology,” SQRL president David Stanfill said. “The added capacity of 16GB HBM2 memory coupled with our industry leading 300W-per-chip design gives our customers unique and unparalleled access to mine even more cryptocurrencies.”

The new JungleCat modules can be used to mine top-tier cryptocurrencies using algorithms like Ethash (Ethereum), Equihash, and Cuckoo Cycle with an outstanding return, in part due to industry leading power efficiency. They also offer tremendous advantages in other data center compute workloads, including video processing, database acceleration and machine learning.

Intel Corporation (NASDAQ: INTC) is an industry pioneer in silicon across multiple verticals, and their collaboration as a supplier puts decades of experience and expertise behind the SQRL team.

“We have been working closely with Intel to optimize our product offerings for our customers’ needs,” Stanfill said. “We’re incredibly proud of the results so far, and we’re excited for the future.”

High capacity 16GB HBM allows the new JungleCat products to keep critical data closer to computational resources, reducing power and ultimately providing superior performance, even for algorithms that utilize significantly smaller amounts of memory.

“This is game changing,” Stanfill continued. “We’ve built products around HBM2 before, but with Intel’s help and the unique advantage of their Hyperflex™ architecture in the Stratix 10 MX products, we were able to take the lessons learned about the unique bottlenecks in our workloads, and bypass them with this advanced generation of product.”

More details about the new products are forthcoming. SQRL will begin accepting orders in March, with shipments expected the same month. Units will ship with support for multiple algorithms, including those already supported by SQRL’s previous BCU-1525 and ForestKitten products.

The company is expecting continued high-demand for these products and recommends interested parties contact [email protected] to begin reserving inventory.
