We can directly accessing Keycloak’s Registration Page without have to go to the Login Page first, and it is quite simple. Here is the URL required to have that condition,
http://localhost:8080/realms/PowerRanger/protocol/openid-connect/registrations?
client_id=my-client-id&
redirect_uri=redhat.com&
response_type=code&
scope=openid
This are achieve by using Keycloak version 17.
