C-Auth

an authentication service for Websites

Every year millions of accounts get hacked, because of weak or leaked passwords. Often the reason for this is, that the website does not store the passwords securely, sometimes even unencrypted.

C-Auth aims to solve this problem by not relying on passwords at all. Instead it uses on-device authentication using biometrics or authentication devices. This way the user does not have to remember a password. This is achieved using the webauthn standard.
