How to implement Auth0 Jwt in my scenario. I have multiple known end users, who hit the server and server validate it. so I implement auth0 machine to machine API application but the problem is I use only one client and secret id in all end users. I want to use different credential on all end users. so how can I implement like this?

Hi @ausaf.hussain

Machine to Machine Applications are typically used when you want to communicate between servers.

It sounds like what you want is to communicate between a client and a server. If this is the case then I would recommend taking a look at [these docs](https://auth0.com/docs/api-auth/grant/implicit) regard communication between a client and an API.

Hope this helps!

Thank you For your response.  
My Client is known (mean credential define by server or auth0) and client app is base on Android and i am not want to use same credential(like client\_id) in all client so in this case, [docs](https://auth0.com/docs/api-auth/grant/authorization-code-pkce) is this the best way to implement.
