About us

At krypt.co we’re building the next generation of mobile-based authentication. Our vision is that authentication should be based on strong cryptography.

Public key cryptography has existed for almost 40 years but it’s barely used to authenticate people. Most people cannot store a long private key in their head nor can they compute digital signatures on the fly. Therefore, we need to store the private key somewhere. It has to be accessible but also kept a secret. At krypt.co we’re tackling this very problem and we believe the smartphone is core to the solution.

Our product Krypton is the first phone-based U2F and WebAuthn authenticator that provides users on the web with easy-to-use, unphishable, zero-touch multi-factor authentication.
