When you use our Passwordless MFA mobile application to login, you use Face ID to unlock the certificate in the hardware backed storage, and then that certificate is used to authenticate user to our platform. Biometrics processing is happening only on end user devices.
I'm the founder of Typing AI Biometrics ( https://typing.ai ). We also applied to YC but we weren't accepted. Typing AI indentifies users by the way they type and can also act as a standalone Passwordless authentication method.
In case that you want to add an extra Multi Factor Authentication (MFA) method to your product offering (typing biometrics user identity check, known as keystroke dynamics), we can arrange an agreement.
We do not touch or manage biometric data.
