Why you should join Keyri

Keyri makes multifactor authentication easy and secure in mobile-first applications. We make a library for mobile apps that, in conjunction with our API, allows users to register and login without a password - using just their phone's biometrics. For web applications, our system enables "sign-in-with-QR" functionality.

We are a security company at heart and believe that a smooth UX is fundamental for ensuring security in the real world.

Our company is well-funded and is working with large financial institutions to serve their millions of users. We are committed to maintaining a culture of excellence, respect, and healthy work-life balance.
