Currently we’re using client id/secret to request M2M token in the client credential flow. I am wondering whether auth0 supports using client certificate to request M2M token? if not, is there other solution we can use on top of auth0 to support this. Thanks.

Hello @gavin3466,

Currently, Auth0 does not provide client certificate authentication feature at the moment and the only way is via the [client credentials flow.](https://auth0.com/docs/get-started/authentication-and-authorization-flow/client-credentials-flow)

If you have a moment, this is a great opportunity to create a feedback request for this feature on our [Feedback page](http://auth0.com/feedback?_gl=1*19ngx4w*rollup_ga*MzEzMjkzMjY2LjE2NzYyNjUzMjQ.*rollup_ga_F1G3E656YZ*MTY3NjYxNDg2Mi4yMS4xLjE2NzY2MTU4NDUuNDMuMC4w&_ga=2.241267275.839291216.1676265324-313293266.1676265324).

Thanks!
