Hello,
I would like to know if Auth0 supports getting a user access_token based on client certificate in the same way it works with DB connections with grant_type = password.
I would expect the user (machine/proxy) to provide a certificate to Auth0 inside a header, nothing else.
Auth0 would validate the client certificate against a preinstalled certificate authority.
It the client cert is OK, then extract the username from the CN to retrieve its data and send it back in a JWT.
Regards
