Verify username and password through rest-api without authentication

I’m trying to make my own Tasklist with react.
I’ve enabled basic authentication in my rest-api now I can’t access to the /Identity/verify end point without providing primary credentials (e.g demo:demo) which it does not make sense.
In the documentations was mentioned the only path that does not require authentication is the “/engine-rest/engine” which lists the engines.
What should I do then?

Any Idea?
I’m alone with this problem?

Are you using Camunda spring-boot deployment?

In that case, you can permit certain endpoint without authentication with the help of spring security.

No I’m not using spring-boot
I just wonder what are the the others doing in this case
