Solr can support JSON Web Token (JWT) based Bearer authentication with the use of the JWTAuthPlugin.
This allows Solr to assert that a user is already authenticated with an external Identity Provider (IdP) by validating that the JWT formatted access token is digitally signed by the Identity Provider.
The typical use case is to integrate Solr with an OpenID Connect enabled Identity Provider.
Please refer to the Solr Ref Guide at https://solr.apache.org/guide/solr/latest/deployment-guide/jwt-authentication-plugin.html for more information.
A User interface for this module is part of Solr Core.
