Hi @juan.caicedo,
Welcome to the Auth0 Community and sorry for the late reply!
Each application in Auth0 issues its own set of tokens, so transferring a token from one application to another for authentication purposes is not a feasible approach. In order for a user not to have to re-authenticate after being already logged in on one application we recommend implementing Single Sign-On.
You can check out this community post that provides information on the matter, as well as multiple documentation links that are relevant for achieving this scenario.
I hope this helps others too!
Thanks,
Remus
