Clef is secure two-factor auth with no passwords or tokens As we move more of our personal information into the cloud, we need security we can actually use. Clef uses the mass adoption of smartphones to make an identity platform for the modern web, creating a totally new approach to logging in online. We've built two-factor authentication that lets sites recognize their users with a wave of their phones. Clef puts secure cryptography in the hands of every user — no weak passwords, frustrating tokens, or clunky dongles.

Secured with Touch ID Every time a user logs in, they will be uniquely identified with their fingerprint using Apple's Touch ID technology. With secure biometrics, you can trust that your users are who they say they are. If a user's device doesn't support Touch ID, Clef securely falls back to a PIN on the device — there's always a second-factor. Learn more about Touch ID Time-tested security Clef runs on an RSA public-key architecture, technology that developers have been using to secure their logins for years. We let the phone handle the hard cryptography and give your users an experience they'll love. See the documentation Fraud detection & monitoring We use location, usage, and hardware data to make sure every authentication is genuine. With each user tied uniquely to a phone, Clef protects your site from fraud and abuse. With our security team handling threats, you'll have more time to focus on product.

Clef Values

Be better today than yesterday Being better is more important than being the "best", because "best" means complacency and better means progress. We are always improving. Improvement requires reflection, so we take ownership of our mistakes and question our habits. Treat others the way they'd like to be treated Our customers and teammates have different needs from our own, so we must consider their perspectives to communicate effectively. We work best together when we empathize with one another, and we create the best product when we understand the people we are building for. Fight the default of exclusion Inequality and exclusion are the defaults of our industry. Without intentional effort, we will inherit those failings and worsen the problem. Building a diverse team is a moral imperative and we build a better business and product by bringing different perspectives to the table. We look for voices unlike our own because they are the only ones that help us grow. Build trust with truth Transparency and honesty are requirements for succeeding with Clef. In order to build a trusting community we give employees and customers deep visibility into how decisions are made and easy outlets to help guide our course. When we build trust through good communication, we create an environment for better communication in the future. We succeed together We fight for Clef because we love the problems we solve and the people we work with. We are most excited when the company’s successes are our own, and when our teammates recognize our contributions. When we’re excited, the hard work we do always has meaning.

Pretty sure this could be a way to make 2 factor authentication easy for exchanges to implement, then maybe we will start seeing less of what happened to blockchain.info and others. Exchanges and wallet providers *need* a secure way to keep their login details from prying eyes, and as far as I can tell Clef is actually a solution. Bitstamp, Coinbase, you guys need to listen and pay attention here.

[YESConnie]

I'm excited that I came across this! CLEF looks absolutely amazing; way better than Authy and Google Authenticator. This can add a cool factor to help bitcoin go mainstream too. Imagine being able to access your wallet with CLEF. Whoever adopts this first will have a great competitive advantage.

[fordlincoln]

I like that Clef is using Public / Private key crypto for 2FA -

[starsoccer9]

Clef makes it easy to replace passwords. For example rather then going to login to bitstamp with your username, password, and then 2fa, you can just login using your phone. It is quick and easy.

[MrDjAK]

Excelent job

[Cryptowatch.com]

Very interesting. Will definately look closer into this. Don't like the fingerprint idea, but I see there's alternatives to that which is good.

Any plans for supporting jolla phones?

[fordlincoln]

Interesting - didnt hear about Jolla phones before this but found that they use Sailfish OS:

"Sailfish OS has the in-built capability to run Android™ apps on your Jolla. So you can continue using your favourite apps like Instagram, Facebook, WhatsApp and Twitter as well as downloading all the latest ones via the Yandex and Aptoide Stores and other Android™ marketplaces."

As the Clef app is on Android, it would appear to work on Jolla - curious about this, please post here if this works for you

Yeah, Clef feels very different than other 2FAs (but in a great way). I'm interested in seeing the growth and expansion of it on many different sites.

Bitstamp would need to add the clef plugin.. And trust the central server...

Can this not be done trustlessly? I mean we are on bitcointalk right?

Any 2FA system should be trustless and open source.

Not every 2FA system is trustless nor open source. Google Auth and Authy are certainly not.

Clef documentation outlines they don't hold any private keys. The private key is kept on your phone and only the public key is shared with the Clef server to authenticate the OAuth handshake.

So they can lure in open source projects and then jack the rates up at will or sell information they gather to seo's? Ya sure

Lure in open source projects? Not sure where that came from as it's purely a 2FA alternative to whats already out there. Atleast they don't share your information without permission.

Clef wave needs to be synced to complete the OAuth at the redirect URL which means that the cryptographic handshake never happens on Clef.

Clef Announces True Logins: the first tool to protect against phishing attacks

True Logins add a simple check when you log into a new computer.
After you sync the Wave, Clef temporarily redirects you to a safe site and your phone asks a simple question to confirm you’re in the right place.
If anything is suspicious, Clef cancels the login and sends you to getclef.com where we can be sure you aren’t being phished.
Otherwise, you’re logged in like normal and we remember the computer so you only have to do the extra step once.

I think the OP needs to outline the business model of Clef. How do you guys pay for all the servers and bandwidth? How do you guys pay for the technical and support staff?
