Hi Naveen
There isn't a TMF Open API for IAM. The TMF720 Digital Identity Management API is used for managing the credentials of a party/partyRole/resource. However, it does not handle the authentication itself. There are already other SDOs that provide APIs to handle this, e.g. OIDC, along with numerous identity providers to handle the authentication.
Good luck
