|
Token Exchange RFC describe an OAuth2 extension to support Token Exchanges.
|
|
|
|
|
With that RFC you could exchange an access token with another one.
|
|
|
|
|
|
|
|
|
|
It would immediately be useful to support the following features:
|
|
|
|
|
|
|
|
|
|
- provide impersonate ability to trusted clients
|
|
|
|
|
|
|
|
|
|
The RFC propose to use the existing ~/token~ endpoint.

Here would be an example for account switching:

The call takes:
|
|
|
|
|
|
2022-04-26 14:26:14 +00:00
|
|
|
- Authorization contain the info about the Client (id + secret)
|
|
|
|
|
- Some JWT signed by the client containing some SecureX ~user-id~
|
|
|
|
|
- optionally a list of scopes
|
|
|
|
|
- optionally some audience

|
|
|
And should return an access token of this user.
|
|
|
|
|
So we could provide a client that would just need to know some user-id to
|
|
|
|
|
be able to get a JWT of this user.

* Token Exchange support Okta tokens
|
|
|
|
|
|

|
|
|
The end goal is to provide a mechanism for a team that support Okta login to
