Pass Trough Authentication without a user registering manually

The customer has a SFDC application and wants to pass trough to our custom web application directly without the user to sign in manually.

  • If SFDC creates a new user they will use our API to create a new user in our Auth0 DB as well
  • They would get a response (a token) to ensure they can login
  • Next time this user logs into SFDC they want to provide a forwarding link allowing them to directly log into our application WITHOUT manual login

Which method can / should we use for this szenario?!
