Re: [ANN] Clef is secure two-factor authentication with no passwords or tokens

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.

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.

i dont think this one is

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.

It's free for users unless you're a website owner.
They get usage analytics -

Projects in Bitcoin that are using it currently:
Koinify.com
Betmoose.com
